Poorly-groomed yet somehow adorable, Wally would rather be playing Banana Blasters or organizing his expired pudding collection than jetting off on some crazy expedition. If there's one thing Wally's good at, it's being a monkey -- he can howl and fling with the best of them.
GASI's esteemed Doctor of Astrophysics, Dr. Chimpsky assigns the Monkeys their highly important missions (which sometimes include getting him more ice when his drink gets too warm) and does his best to keep them on track when they get distracted.
Older brother Gus wants nothing more than to be a hero, but he can't always put aside his monkey instincts. The closest thing the ship has to a captain, he takes being a GASI cadet very seriously -- well, when he feels like it.
Tasked with keeping Gus and Wally on course, there's nothing this robot wouldn't do for his beloved monkeys -- after all, he's programmed that way. He's quite the charmer, too -- from the fridge to the blender to the vending machine, there isn't a ladybot on board whose circuits he hasn't made beep a little faster.
