It's very hot in Shuggazoom City. So the monkeys decide to cool off with a swim, and everyone seems excited, except for SPRX-77 and Chiro. But the water begins to rise, and soon floods the city. On a rescue mission, Chiro's fear holds him back once more, and no doubt would he have drowned if the team had not saved him at the last minute. Deciding to get to the source of the problem, they plunge down to the deep depths of Shuggazoom's water base, to find that the pillars holding everything up are terribly corroded, and the massive dents look like teeth marks. The monkeys find the source, a giant water monster, which with Chiro's help get's killed, and the city is saved.
