In this, the very first episode of Hanna-Barbera's first TV show, our heroes read reports of spacecrafts from other worlds. One such ship bears a bead on Ruff and Reddy as they nap and take them aboard the craft.

Ruff and Reddy awaken from their nap to find they have been taken hostage by the ship from space.

Ruff and Reddy's robotic captors pursue them with a gun that Reddy gets hold of.

On the metal planet Muni-Mula ("aluminum" spelled backwards), Ruff and Reddy face a two-headed metallic chieftain called "The Big Thinker," who takes our heroes to be assimilated as metal clones.

The duplicating process of Ruff and Reddy begins. Reddy tries to intervene but becomes a robot himself after he gets zapped by the robot brain implanter.

Ruff tries to help Reddy but is followed by a roving mechanical spy.

Reddy gets accidentally mesmerized by the brain waves and under orders of the Big Thinker takes Ruff captive.

Ruff and Reddy discover a scientist, Professor Gizmo, in the dome of the Big Thinker. Gizmo tells how he blasted off in his homemade rocket and was taken prisoner in Muni-Mula.

After Reddy destroys the slumbering inner works of the Big Thinker, he, Ruff and Gizmo are hunted down by a huge robot centurion.

Reddy, having given the Gizmo 2 ship a boost, is left behind on Muni-Mula. Ruff and Gizmo go back after him but are confronted by a flying attack squad of Muni-Mula robots.

Gizmo confuses the Muni-Mula attack squadron by cloaking the Gizmo 2 craft in a dark cloud. Meanwhile, Reddy takes off in one of the metal squadron's head propellers and is mistaken by Gizmo to be one of the metal men.

Gizmo rescues Reddy from his freefall, but now the Gizmo 2 rocket ship is on a collision course with a meteor.

The meteor hits the Gizmo 2, sending it and our heroes on a crash course to Earth, where broadcast media reports its arrival as if it were a UFO invasion.

A baby elephant escapes from a circus and requests Ruff and Reddy to take him home in Africa.

Ruff, Reddy and Pinky board Voo Doo Queen and get locked on board.

Captain Crossbones Jones forces Ruff, Reddy and Pinky to be his crew, but they start to escape.

Ruff, Reddy and Pinky get stranded at sea trying to escape and then they start to sink.

Ruff, Reddy and Pinky cruise to an island. Ruff gets captured whilst exploring.

A hunter named Harry Scary uses Ruff as bait to lure a lion, but the lion and Ruff take off.

Ruff rescues the lion and Harry Scary reveals himself as an elephant hunter.

Before Harry Scary can shoot Reddy, the lion comes to his rescue and all three run for it.

Ruff, Reddy and Pinky escape from Harry and try to get across a river. Their escape log turns out to be a crocodile.

Reddy gets trapped with the crocodiles after saving Ruff and Pinky and Harry Scary comes round.

Ruff and Reddy follow Harry Scary who took Pinky away. Harry Scary makes Pinky lure his mother into a trap.

Harry Scary gets all Ruff, Reddy, the lion, Pinky and his mother exactly where he wants.

The tables turn because of Harry Scary's empty rifle. Ruff and Reddy stowaway back home.

Reddy wins a trailer, so he and Ruff take a vacation to the Grand Canyon. An accident, however, sends them to the ghost town of Gruesome Gulch.

Ruff and Reddy are spooked by Gruesome Gulch's ghosts, which are actually fake ones manipulated by two rustlers.

Ruff and Reddy meet Wooly, a sheepdog whose flock of sheep is being mysteriously stolen. Reddy is coerced into posing as a sheep to catch the thieves.

The sheep thieves in a helicopter pluck Reddy from the flock and take him to Gruesome Gulch.

The thieves, sibling outlaws Killer and Diller, aim to sheer the sheep of their wool, which threatens Reddy's cover.

Reddy's cover is blown. Killer and Diller tie him up, place him in a mine's ore car and sends him towards an unfinished section of the trestle.

Ruff and Wooly rescue Reddy, and together the three heroes head back to Gruesome Gulch to find Wooly's sheep.

As Ruff, Reddy and Woolly pursue the Texan Twins, they get flat tires and take the helicopter for transport.

Reddy lands on the truck's roof where he holds Killer at gunpoint. But Reddy ends up getting clobbered by a tunnel's low clearance.

On Killer and Diller's secret ranch, the Double Cross, the sheep spell out the word "help" for our heroes. Unfortunately, their copter has run out of gas.

Thanks to the sheep, our heroes find the copter's safety chute for landing safely. Once landed, Killer and Diller capture them and lock them up.

In accordance with the rules of the west, Wooly demands that he and his friends fight for their lives. So he volunteers Reddy to a duel with Killer and Diller.

Reddy nervously faces Killer and Diller in the duel, but he has an ace in the hole: Ruff in his cowboy hat with a second revolver.

At an aquarium, a baby seal follows Ruff and Reddy home. A chase ensues when the aquarium announces a reward for the seal's return.

The chase for the seal leads to a pier near the ocean, where someone underwater is in trouble.

The metal monster Ruff and Reddy hoist to land is a diving bell, and in it is Professor Gizmo, who is mining for gold beneath the sea. Meanwhile, a periscope spies our heroes.

The periscope belongs to a mysterious submarine that trails Gizmo's ship, the S.S. Leadbottom, which is on the way to a pirate's treasure.

The submarine captures Gizmo's diving bell with a giant magnet and takes it to a mysterious grotto.

Captain Greedy and Saltwater Daffy imprison Ruff, Reddy and Dr. Gizmo. Then the seal arrives to help them.

The seal helps Ruff, Reddy and Gizmo escape and leads Greedy and Salt Water Daffy on a merry chase.

The crew attempts to escape on Captain Greedy's sub, but are recaptured. Greedy forces Ruff and Gizmo to mine for treasure while Salt Water Daffy keeps Reddy and the seal at bay.

The seal saves Reddy from drowning but Saltwater catches him.

The seal and Reddy manage to get away from Saltwater but are tailed by a shark.

Reddy and the seal escape but are being pursued by a shark. A friendly whale scares off the shark and takes Reddy and the seal to help Ruff and Gizmo.

The seal boards Dr. Gizmo's sub with Ruff inside it and prepares a surprise for Greedy.

Greedy gets all the gold, but when he makes Reddy give back the doubloon he was going to keep as a souvenir, Greedy's ship sinks from the weight.

Ruff and Reddy help Dr. Gizmo to protect his valuable Chickasaurus egg from some thieves.

Killer and Diller in mummy guises swipe the Chickasaurus egg, wrapping Ruff and Reddy in their mummy wrappings.

Gizmo, Ruff and Reddy pursue Killer and Diller, but the Chickosaurus egg tumbles out of their truck and towards our heroes.

The Chickasaurus falls down a cliff and cracks. When Ruff, Reddy and Dr. Gizmo reach the egg, it begins to hatch.

The Chickasaurus has only managed to partially hatch from the egg. When it does hatch Killer and Diller arrive.

As Killer and Diller try to take the Chickasaurus away, but Ruff, Reddy and Dr. Gizmo get tangled with the running Chickasaurus.

As the Chickasaurus becomes airborne, Killer and Diller follow by helicopter all the way to a secret prehistoric jungle.

After a Brontosaurus blows Killer and Diller away, Ruff and Reddy try to flee from the jungle but they run towards a T-Rex.

Ruff, Reddy and Dr. Gizmo take shelter in a cave from a T-Rex. In the darkness they see a pair of eyes.

Ruff, Reddy and Dr. Gizmo are met by a cave boy called Ubble-Ubble, who knocks out the T-Rex. Killer and Diller kidnap Ubble-Ubble.

Ubble-Ubble bats Killer and Diller but they recapture him and Ruff, Reddy and Dr. Gizmo are confronted by a sabre-toothed tiger.

Ubble-Ubble lands in the chickasaurus nest where the chickasaurus is nursing a pair of eggs.

Killer and Diller try to steal the chickasaurus eggs but are flattened by Reddy. Ubble-Ubble joins the team back home (where Gizmo has presumably adopted him) and becomes a little league baseball sensation.

At the Grand Canyon, Ruff and Reddy hear of rumors of a pint-sized pony and as to the validity of their existence. Harry Scary hears of the rumors as well.

Harry Scary sends Reddy on his out-of-control donkey Poco Loco, who disappears in a burrow.

Ruff and Reddy make their way through the burrow where they see Poco Loco has made friends with a pony no bigger than Reddy's hand.

Harry Scary tracks the Pee-Wee Pony's hoofprints, and Pee-Wee leads Harry on a chase.

Harry lassos Pee-Wee but the pint-sized pony refuses to give up.

Pee-Wee escapes Harry's clutches and hides out in Reddy's hat. Poco Loco gives it to Harry "in the end."

Harry Scary tries to hold our heroes at gunpoint in exchange for Pee-Wee, but Poco Loco steals Harry's gun. As Pee-Wee heads back home, Harry lies in wait for him.

Harry Scary captures Pee-Wee in a sack. Pee-Wee's mother runs to alert Poco Loco, Ruff and Reddy.

Harry Scary escapes with Pee-Wee in a motorboat, pursued closely by Ruff and Reddy.

Harry takes Pee-Wee to his carnival, where he plans to get rich off using the pint-size pony as an attraction.

As our heroes head for Harry Scary's carnival, Pee-Wee goes through indignities as a performer in Harry's show.

Pee-Wee is locked in a strongbox as Ruff, Reddy and Poco Loco infiltrate the carnival.

Disguised as clowns, Ruff and Reddy rescue Pee-Wee, while Poco-Loco sends Scary into orbit with a good donkey kick.

Thinking they've subdued a burglar in the house, Ruff and Reddy discover a strange little man.

The visitor is a leprechaun, who filches Reddy's gold watch. How can he and Ruff explain this to the police?

The leprechaun tells our heroes of the Goon of Glocca Morra, a greedy being who has taken their princess for ransom and just keeps all the gold.

The leprechaun takes Ruff and Reddy to Ireland where the princess is being held captive at Banshee Castle.

Reddy's climb to the castle ends in a moat, leaving our heroes to alternate means of entering.

Ruff is slingshot into the castle where he goes missing. The leprechaun shrinks Reddy to his size as the pair venture to the castle.

The leprechaun and Reddy go across the moat and into the castle where Reddy is chased by the Goon's cat.

Reddy finds Ruff locked in a cell, then has to get by the cat in order to get to the cell key, held by the Goon.

Reddy sets eyes on the Goon of Glocca Morra as he makes a bid for the cell key.

Reddy frees Ruff from his cell and together they flee from the Goon.

Ruff hides in a turret, and the Goon plans to blast him out with a cannon in which Reddy is hiding.

Ruff and Reddy search the Goon's treasure room for the princess.

Reddy clobbers the Goon with a gold piece and with Ruff discovers the princess had been imprisoned in the Goon's hat. Reddy is returned to normal size while the Goon is shrunk and made a playtoy for his own cat.

With help from Ruff and Reddy, Professor Gizmo plans to launch a rocket to the moon. However, things go wrong when Reddy launches it prematurely.

As the rocket's third stage engages its parachute, it falls to earth and is blown by upper level winds off course.

The capsule lands in a frozen diorama. Meanwhile, Captain Greedy and Saltwater Daffy track the capsule, full of valuable instruments, in their submarine.

Reddy's ire is aroused when he sees a Viking boy being chased by a polar bear. But the slick ice surface isn't conducive to head-to-head battle.

Ruff, Reddy, Gizmo and the Viking child, Olaf, make it to the capsule, but Olaf wants to go back out and fight the bear.

Olaf summons his pet falcon to ward off the bear, who turns tail and runs away.

While Ruff, Gizmo and Olaf search for food, Captain Greedy and Saltwater Daffy surface.

Olaf calls upon his falcon again when Captain Greedy and Saltwater Daffy hold Ruff and Professor Gizmo hostage.

Captain Greedy forces Gizmo to take him to the capsule, in which Reddy is sound asleep.

Olaf launches an offensive on Greedy and Daffy while Olaf's falcon alerts Reddy.

Reddy clobbers Saltwater Daffy, but Greedy, smelling something rotten in Denmark, sends Gizmo in to get clobbered as well.

Olaf gets hold of Captain Greedy's gun, and it goes haywire. Once it becomes loose, a battle for it ensues, ending with Greedy holding Reddy at gunpoint.

Greedy confiscates Gizmo's capsule equipment, but Olaf gets the drop on him with a horde of Vikings.

A swamp pirate, Jean La Fitt, runs amok and spoils Ruff and Reddy's fishing trip.

Deputized by Sheriff Cotton E. Pickens, the boys and Pickens are pursued by an alligator.

The alligator, knocked out by La Fitt, makes friends with Ruff after he revives him.

Ruff names the alligator Chopper, and adds him to the pirate posse.

La Fitt is cornered but makes an escape.

Ruff, Reddy and Sheriff Pickens try to find La Fitt's hideout.

La Fitt turns his cannons on our heroes.

LaFitt creates a whirlpool to stop Pickens, Ruff and Reddy.

Our heroes look for LaFitt's hideout.

Cotton Pickens nearly meets his doom.

Chopper nearly destroys the raft our heroes are using.

Ruff turns Chopper into a makeshift whooshmobile.

Chopper helps with the final corralling of LaFitt.

Ruff and Reddy are trainbound for Spooky Rock where a rendezvous with Professor Gizmo is to take place

Gizmo presents his invention, a mobile borer with which he plans to gather substrata data in the mountains. The outlaws Killer and Diller follow our heroes.

Killer and Diller watch in amazement as Gizmo tests out his borer.

Satisfied with the borer's success, Killer and Diller plan to hijack it with the plan of finding the Lost Dutchman mine.

Killer and Diller show up and force Gizmo to drive the borer to the Lost Dutchman mine.

After a lights-out fight, Ruff gets the drop on Killer and Diller. Reddy ties them up and transports them away to the nearest jail.

A bump in the road causes Killer and Diller to bump off Reddy's car. The outlaws make a getaway with Reddy in pursuit.

Jumping off a railroad bridge, Killer and Diller land in a river. Reddy returns to the borer.

Once the treasure's location is exposed, Greedy and Daffy return.

Greedy and Daffy obtain the treasure, which winds up getting swallowed by a whale.

Ruff and Reddy answer an ad for the promise of travel and adventure. A wily professor tricks them into taking off in a rocket ship.

The professor instructs Ruff and Reddy to gather information on the moon as they orbit around it.

An errant button press sends the rocket off course.

The rocket heads for a mysterious planet.
