Das virtuelle Surfen in Ms. Roskoffs Simulator ist Josh, Toby und Bobby zu öde. Sie träumen vom Kometensurfen, einer angesagten aber gefährlichen intergalaktischen Sportart. Da kommt es wie gerufen, dass Brett mit seinem selbstgebauten Teleskop „Brettoskop 9000“ einen bisher unregistrierten Kometen entdeckt. Josh, Toby und Bobby machen sich heimlich auf den Weg zum Kometen. Dieser entpuppt sich jedoch bald als Lockmittel des einstigen Kometen-Surf-Stars Johnny Stardust. Er kann es nicht ertragen, dass sein Stern am Sinken ist und versucht, mittels des Pseudo-Kometen potenzielle Konkurrenten anzulocken und für die Zeit des intergalaktischen Surfturniers auszuschalten...
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 the activity is strictly prohibited by Principal Kirkpatrick. Regardless, that night, they pull out their boards and sneak off to the comet zone. As they hit the surf, Bobby and Josh each try to impress Toby. But ultimately, none of their efforts are very impressive as a massive uber-comet appears and swallows them whole! The next day when they aren’t in class, Principal Kirkpatrick sends their remaining teammates on a mission to try and find them. Clues lead Yoko, Brett and Kimball to the mysterious uber-comet. It turns out that the comet is actually manmade. And it’s being operated from the inside by the bitter alien pioneer of the comet surfing craze, Johnny Stardust. Because comet surfing has become so popular, all of the younger participants have gotten much better than the alien. So much so, that he has lost all of his intergalactic sponsors. His plan? To use his man-made comet to capture the competition and then catapult them into deep space so that the spotlight will once again shine on him. Can the GH students stop this insane alien dude before it’s too late? In a b-story, Bobby and Toby take their competitive spirits to a whole new level and Brett creates a Brettoscope 9000.
