Sea rhinoceroses are dangerous wild creatures who first appear in the episode "The Camping Episode" and later in the online games Camping Chaos! and SpongeBob's Atlantis SquarePantis Squareoff. The sea rhinoceros is voiced by Dee Bradley Baker.
The sea rhinoceros has a large sea turtle body, a shark tail, two spikes on its back, a rhino head, and dark gray skin. They are attracted to the sound of a sea bear attack and are about twice the size of a sea bear.
The only known way to prevent a sea rhino attack is to wear anti-sea rhinoceros undergarments. Anti-sea-bear circles will not provide protection from these creatures, as they are instead designed to protect people from sea bears.
Role in episode
One appears at the very end of the episode after the sea bear attacks end, as it was attracted by them. SpongeBob and Patrick do not have to worry about the sea rhinoceros attacking them, because they are wearing their special anti-sea rhinoceros undergarments. However, Squidward unfortunately does not have a pair on, making him an easy target for the rhino.
