When GH receives a distress call from a nearby friendly planet, Josh, Yoko and Brett are sent to help the hapless robot aliens who live there. You see, the computer that runs their weird planet (they're too inept to do it themselves) has broken down and they need help fixing it.
When a Galaxy High satellite picks up what appears to be a distress signal, both Josh and Bobby's teams (Josh, Yoko and Brett/Bobby, Kimball and Toby) are sent together (in one ship) to check it out.
While on a mission, Josh, Yoko and Brett stop at a nearby "truck-stop" (think: cool, kitschy, David Lynch-style intergalactic diner w/gas station) to gas-up and, to their surprise, find that the place is bustling with activity.
The latest craze that's sweeping the Galaxy is comet surfing - a wild sport where teens use a high-tech "space board" to ride the tail wave of a comet! Josh, Bobby and Toby are all stoked to try the sport, but unfortunately for them, the activity is strictly prohibited by Principal Kirkpatrick.
Josh, in a selfish effort to "upgrade" Fluffy, (so that the ultrapet can do his homework, wash his laundry, clean his dorm room and complete all manner of other unpleasant-to-a-teenage-slacker-boy activities), sneaks into Principal Kirkpatrick's office and hacks into the GH mainframe.
When a famed, intergalactic virtual gaming arcade opens in their part of the galaxy, Brett, Josh and Yoko rush to check it out - after all, it's rumoured to contain the most challenging games in the entire universe!
When Josh, Yoko and Brett take a wrong turn on a routine patrol and suddenly find themselves lost in unfamiliar space territory, they're quickly ambushed and captured by an IAC -- an Intergalactic Alien Catcher.
It's early morning and Josh, Yoko and Brett are on a routine patrol when they get a call from Principal Kirkpatrick. Seeing that they're using their time to goof off, PK instructs them to return to Galaxy High.
When Josh's team is sent on a mission to investigate a series of explosive disturbances in outer space that are sending shockwaves throughout Galaxy High, the gang comes across a small planet with two warring sets of alien neighbours on it.
When Brett discovers (to his utter shock and horror) that entire planets in the galaxy seem to have inexplicably gone missing (along with the aliens which inhabit them), his team is quickly sent to investigate the disturbing phenomenon.
The mega-ultrapet is released, a new model that threatens to replace Fluffy. To test the new ultrapet, Josh, Yoko and Brett are sent to an intergalactic junkyard on a mission, but things get complicated with the arrival of a new threat.
In a teaser, we see a dilapidated space craft appear in the outer reaches of Earth's atmosphere -- a faded Galaxy High symbol on its hull. Meanwhile, while out on patrol, Josh, Yoko and Brett meet a group of alien teenage space racers and are immediately drawn to them.
Recap of previous episode. Even though they are technically expelled, this is one mission the gang has to carry out. Josh, Brett and Yoko follow a trail of clues which leads them to a strange planet on the edge of the universe.
