A fitting for new space-suits reveals that Gus's tail has grown just enough to classify him as a rare long-tailed monkey, which attracts Gamester X, an alien determined to add Gus to his collection.

Lord Peel is out to expose the Rocket Monkeys' incompetence on his new tell-all television show, and the resulting backlash has Dr. Chimpsky insisting Gus and Wally change their ways.

Wally sets out to return the delicious spirits of every banana he's eaten to their home planet.

The Monkeys mom comes to visit.

A short-tempered robot named Belindor steals Yay-Ok's "robo-mojo" as revenge for ignoring her in high school.

Thanks to the monkeys, Chimpsky loses his job and is demoted to a Jr. Jr. Jr. Rocket Monkey 3rd Class. Gus and Wally take advantage of their 2nd class status and make the former GASI chief do their bidding.

The citizens of GASI headquarters start disappearing by a bright blue flash and the monkeys plus YAY-OK must save them. The citizens of GASI headquarters had also turned into princess monsters created by an evil princess named Princess Monstare. Eventually YAY-OK tries to fight her, but she turns into a robot with him and the monkeys must save him and stop her.

A doodah gives Gus and Wally one of his wish feathers as a reward for saving his life. But the duo want more feathers, so they put the bird-like alien through several dangers in order to save him again and again.

Gus and Wally have a new and very important mission: build a protective orb around an extremely unstable quasar. After they made the orb as best as possible, they just realize the door knob is missing and leaving them stuck inside the sphere as well.

When Yay-OK's younger sister comes to visit, he tries to keep her away from Gus and Wally.

After an epic war between robots and bananas breaks out, YAY-OK puts the monkeys into a deep cryogenic sleep to prevent them from suffering, during a war between bananas and robots. The monkeys sleep for 1000 years and YAY-OK and Lord Peel fight.

Deep Space Dave and the Purple Puzzler aren't talking. If the monkeys ever want to see their favorite show again, it's up to them to reunite the stars.
