The snow sponge is an animate snowman who is found in the Arctic tundra. He only appears in the episode "Out of the Picture."
The snow sponge is a snowman who resembles SpongeBob. The body is made of snow packed into a rectangular prism and has sticks for arms and legs. He wears a black top hat with a gray band on his head and a red and yellow-striped scarf around his body. He has two black stones for eyes, multiple smaller stones that form a smile, and a carrot for a nose.
Role in episode
While Squidward is delivering food in the Arctic, he is blown of a cliff by the wind and lands next to the snow sponge. He mistakes it for SpongeBob, who appears behind him with a large ice cube. After putting the ice cube in his mouth, SpongeBob helps Squidward out of the hole he is in.
After they leave, the snow sponge suddenly comes to life and starts walking past the hole Squidward landed in.
Even though it is only the appearance of an inanimate object, the snow sponge can move.
