Engines are revving up for a giant speedboat race through the Florida waterways. Unfortunately, the race threatens the endangered manatees who live in these backwaters.

Only, this time they get some unlikely help from Wheeler's favorite TV stars, Danny Dazzleduff and Belinda Bubblebutt from Babe Watch, when they discover that Hoggish Greedly is behind a plan to get rid of the manatees.
