In one of Mizzipotazia's underwater worlds, Mizzi Mozzi and friends embark on a daring adventure to save the Mesmerizing Metiklated Mermodians, who have lost their ability to swim. With the help of floaty rings, a trixie klayke, and their wits, the friends outsmart the treacherous Hamma-Heady Drid-Lix and Rooffless-Tooffless Kroko-Drilie, returning the precious Tuffan-Shineeum scales and restoring peace beneath the Makaronean Sea.
