The episode begins with Sailor jumping into a small pond, apparently having a relaxing swim. He tries to encourage a white and purple cat named Shy to jump in. She refuses, pointing to a "No Swimming" sign. Despite this, Sailor still encourages her to jump in. But he will soon learn there's a reason why the sign is there.

After Sailor encourages Shy to jump in again, bubbles start to form around him. Suddenly, a bunch of vicious piranhas jump out of the water and start attacking him. Shy stands in shock, frantically looking around while trying to find a way to help her friend. Next, Sailor starts getting tossed around like a beach ball by a couple sea lions. Shy attempts to help, but she doesn't do very well, as she tries to reach Sailor with a short stick from a far-away tree. One of the sea lions' tosses Sailor, who is now slightly battered, back on land. Before he gets the chance to do anything, an alligator pops out and chomps on him, leaving a bite mark in the ground that is now part of the lake, indicating the presence of a forming sinkhole. The alligator resurfaces and Sailor struggles in vain to keep its jaw open. Shy, who just thought of something, tells Sailor to stay there while she runs off.

Sailor, now missing the lower half of his body and brutally injured, starts crawling away. But before he can go far enough, a giant whale pops out and lands on top of him, crushing and killing him in a pile of blood and body parts. Shy, who is now holding a life preserver with a rope, throws it onto Sailor's crushed remains. Realizing that she was too late to save her desperate friend, Shy starts pulling back the life preserver while laughing nervously to the audience.
