Abominable Snow Mollusk

The Abominable Snow Mollusk is a large sea monster that appeared in the SpongeBob SquarePants episode "Frozen Face Off".

Biology
The creature has greyish white skin, with four long tentacles that serve as arms. She also has fur around her neck, ears in the shape of fins, sharp teeth and light yellow eyes. She also has multiple tongues that can grab thing each as snow which she shoots out of her mouth. It appears that her digestive system isn't very efficient, given that Mr. Krabs' crew was swallowed by her and survived after going the entire way through it.

History
Mr. Krabs first encountered the Abominable Snow Mollusk back when he was sailing his ship through some lagoon where he and the crew were then swallowed whole by the monster. And how did they escape the creature's stomach? Well, according to Krabs himself, he and his crew had to "wait for nature to take its course". SpongeBob and the gang ran into the beast on a snowy mountain area where she got to taste one of Patrick's gummy worms. The monster soon followed then to Bikini Bottom where she then mistook Plankton for a jelly bean and ate him.
