Mochi becomes an online celebrity when Honey Lemon posts a video of him slow clapping. He becomes so popular, that Mr. Sparkles, the crazy game show host of Maximum Insane obstacle Challenge, loses his fame. Consumed by jealousy, he kidnaps Mochi and threatens to send him into space unless Go Go competes in a game. Hiro meanwhile tries to come up with a fast solution to deliver the team's super-suits during an emergency. When Mochi is in danger, Hiro builds a new robotic invention called Skymax. It rescues Mochi and becomes the team's new suit delivery system.
At the end of the episode, Sparkles is overjoyed after knowing his unfair obstacle challenge got ten million views, stating "Everyone wants the sparkle", while seemingly having no idea that he's now a wanted criminal rather than a celebrity.
