It's time for Seaweed Elementary's annual talent show, but Squizzard can't decide on an act. He's too distracted by the fact that it's also prank week! And he has some fin-tastically silly pranks planned. But his friends have a few tricks up their sleeves, and soon the joke is on Squizzard. Can he survive the prank war, or will he lose his crown as the reigning class clown fish once and for all?
