Sea bears are large piranha-like fish species with grizzly bear heads who are known for attacking. Sea bear first appears in "The Camping Episode."


They are dark green, brown, beige, and greenish-yellow with claw-tipped front fins and the head of a grizzly bear.

Ways to attract a sea bear

The following are ways that attract the sea bear:

  • Playing the clarinet badly as Squidward did.
  • Waving a flashlight back and forth really fast (Patrick says flashlights are their natural prey)
  • Stomping the ground (SpongeBob says they take it as a challenge)
  • Eating cubed cheese; sliced is safe
  • Wearing a sombrero in a goofy fashion (such as upside down or tilted)
  • Wearing clown shoes
  • Wearing a hoop skirt
  • Screeching like a chimpanzee (from how SpongeBob and Patrick say "never, ever, ever," this is a very big attractor)
  • Running (makes them attack one again)
  • Limping (worse than running)
  • Crawling (even worse than limping)


Sea bear attacks are preventable by drawing an anti-sea-bear circle in the sand. However, drawing an oval will not work. They also seem to love tummy tickles and jellyfish jelly.


Though it's credited that Dee Bradley Baker voiced the sea bear, additional sounds were from archival recordings from Thurl Ravenscroft (original voice of Tony the Tiger), James MacDonald (former voice of Mickey Mouse), Clarence Nash (original voice of Donald Duck), and Candy Candido (miscellaneous voices in Disney movies and attractions). The sounds of the sea bears' attacks attracts sea rhinoceros.

Role in series

"The Camping Episode"

A sea bear is the main antagonist of this episode.

Squidward did not believe in the sea bear's existence before he was attacked by one in this episode. However, SpongeBob and Patrick are fervent believers, having read about them in the Bikini Bottom Inquirer and Fake Science Monthly, which are both tabloid magazines. The sound of a sea bear attack also attracts the sea rhinoceros.
