Hippoman - S2.E22

Shu, Bouquet, Marumaro, and Noi help two female bakers prepare a cake display for a town event to earn some money. But there are delays in the kitchen, and Noi and Bouquet has to stall the crowd until they are done. With help from Shu, they complete the cake display and use Saber Tiger to transport it there. When Blue Dragon bursts out the cake scaring the kids, Bouquet improvises by having Hippopotamus dress up as a superhero called Hipopotaman to fight Blue Dragon. Marumaro has Saber Tiger join the act to help Hipopotaman fight Blue Dragon. This only agitates Blue Dragon in the end who makes sure the party "ends with a bang".
