Brett's Brain

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. The computer that runs their weird planet has broken down and they need help fixing it. Only... when they realize that Brett is even smarter than their aging mainframe, their intentions go from innocent to evil. Once Brett returns to GH, the aliens follow... and steal Brett's brain right out from inside his head - turning him from GH's brightest student to the dimmest. Can Josh and Yoko help their teammate before the damage becomes permanent!?! In a b-story, Yoko protests the new capsule-style food in the GH cafeteria.
