This is the page about the sea monster from "Prehibernation Week". For other uses, see Sea monster (disambiguation).

The sea monster is a character who only appears in the episode "Prehibernation Week."


It is a big, dark green, elephant-like monster with a long trunk and three eyes.


When Sandy orders the Bikini Bottomites to go look for SpongeBob, she tells the other people to check inside a moist cave she found, but said moist cave is revealed to be the elephant-like trunk of a sea monster of some sort.


  • Due to having a trunk like an elephant, the sea monster could be an elephant fish or possibly a spoof of it.
