The Abominable Snow Mollusk has a grayish-white body with tentacles serving as arms and legs. She also has fur around her neck, fin-like ears, really sharp teeth, and yellow eyes.
Mr. Krabs has mentioned that he once encountered the Abominable Snow Mollusk in his past and that he and his crew were eaten by the creature. They had to "wait for nature to take its course"' 'in order to escape its stomach.
When SpongeBob and the gang escaped the Abominable Snow Mollusk, it got the taste of Patrick's last gummy worm. It was then that the monster earned a craving for sweets. When they encountered the monster again, she ate the jelly beans in Patrick's pocket. It then ate Plankton thinking he was a jelly bean.
She is the third creature to be attracted to Patrick because of food. The first was Gary in "Dumped" (because of a cookie in Patrick's pocket), and the second was a Lion Fish in "Spongicus" (because of blood sausages hanging from Patrick's neck).
Her name is a parody of the Abominable Snow Monster from Rudolph the Red Nosed Reindeer.
