Sea bears are large piranha-like fish species with grizzly bear heads who are known for attacking. They first appear 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 your 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 you 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 honey.
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.
