The Sea Rhinoceros is a fictional creature briefly mentioned and shown in "The Camping Episode". He is a large shark with a body like a turtle and a rhinoceros's head. In order to protect yourself from him, you have to wear Anti-Sea Rhinoceros Undergarments. An Anti-Sea Bear Circle won't protect you (they only protect you if the Sea Bear tries to attack you). These creatures are attracted to the sound of a Sea Bear attack, possibly picking up dead meat (like vultures), if the sea bear has killed and/or eaten anything and has something left over. They are easily twice the size of a Sea Bear. The Sea Rhinoceros are voiced by Dee Bradley Baker. The Sea Rhinoceros is the secondary antagonist of The Camping Episode.
The Sea Rhino has a large sea turtle body, a shark tail, 2 spikes on his back, a rhino head, and grey skin.

Hearing the sound of a Sea Bear attack
The only known way to prevent a Sea Rhino attack is to wear Anti-Sea Rhinoceros Undergarments. They are just any underwear. Anti-Sea Bear Circles won't protect you.
