The Red Guy is sick of being foiled by Super Cow, so he opens up a laundrimat for super heroes, in hope to find out who she really is. It doesn't work, so he goes to Cow and Chicken's house, and kidnaps Cow. Chicken then goes to the rescue as Super Cow for her.

Cow and Chicken go to the arcade, and play the time machine. They find themselves back in a deserted time, where The Red Guy introduces them to the primortial soup. But when Cow accidentally drops her quarter into it, everyone in the present time has quarters for heads. Cow and Chicken must go back into time again to stop her.

Chicken, Flem, and Earl play a game of kickball. Cow's udders kick the ball into the bushes, where Chicken, Flem and Earl discover a laughing puddle. After Flem and Chicken run back out, they forget the ball, and go back to discover that Earl is in the puddle. Chicken sends Flem after him, and he is stuck too. Chicken then gets Mom and Dad, who jump into the puddle, and Chicken drops Cow in there to save everyone. Chicken is then the only one left, until he discovers the puddle is a doorway to Boneless Chicken's nightclub.

Cow and Chicken's class go on a field trip to the Cometorium, where Chicken is bored stiff. After getting hit by one of Dad's golf balls (he was golfing right next door), Chicken hangs it in front of the telescope; soon, the whole town is in panic of the arrival of ""Dad's Ball Comet"".

The Red Guy sneaks a crow egg under Chicken's covers while he sleeps. The next morning, Cow and Chicken find the egg, and Chicken comes to the conclusion that he is actually a girl. So, it's egg sitting for Cow and Chicken, until the egg hatches and a baby crow comes out. Now Chicken comes to the conclusion that he isn't even a chicken.

A group of female bikers break into Cow and Chicken's house, and start gnawing on their carpet. One of the bikers has a crush on Cow, and invites her to join the Buffalo Gals. It's up to Chicken to save his sister.

The Red Guy is depressed because no one will play with him. After seeing Cow has Crabs the Warthog, he wants to play with her because he has Crabs's doll house. When he askes to play with Cow, she tells him not if he was the last man on earth. With that he locks the entire world in a trailer, and is the last man standing: but Cow still won't play with him.

Chicken tells Cow that she's not artistic, so she in return, sculpts a seal out of a stick of chewing gum, and an entire machine full of bubblegum balls. Cow wishes that her chewing gum seal, whom she names Chachi, was real. Suddenly, a wishing star grants her wish, and Chachi is a real, miserable, ho-hum seal.

It's almost arbor day, and Mom and Dad are feeding their pet piggy pennies so they can crack him open on arbor day. Meanwhile, Cow and Chicken are craving ice cream, and try to chase down the ice cream man (Red Guy).

Dad loves shopping for Mom's stuff. He runs off to get a manicure for her, while Cow and Chicken pay for the other items. The censors go off when Cow passes through, so Red Guy, as a mall cop, chases Cow and Chicken all over the store. Cow learns that the censors have been broken for weeks. Red Guy walks through, and is arrest by the REAL mall cops.
