While making some roller skates, Manny and Frida earn money for finding the town's lost pets so they can buy Luxe roller skates and scooters then earn a bigger cash reward if they return a Chihuahua named Taco to his rightful owner.

Manny cares for the town's mascot Zebra Donkey but after accidentally killing him, Manny and Frida use Sartana of the Dead's Golden Guitar of Doom to resurrect him, unaware of the grave consequences.

Manny and Frida accidentally ruin a group of geeky kids' game night but when The Mustache Mafia attack, they must work together to defeat them.

Manny is tired of being a kid so he enlists the help of Dr. Chipotle Jr. to give him a sentient mustache named Raul in exchange for his El Tigre belt.

Manny is rejected as a hero by other superheroes while attending a superhero convention. But when Sartana Of The Dead and other supervillains run amok and trap the heroes at the convention, it is up to Manny to prove them wrong and save the day.
