It's too dangerous to play the clarinet badly out here in the wilderness, it might attract a sea bear.
— SpongeBob telling Squidward about the sea bear, "The Camping Episode"

Sea bears are a large piranha-like fish species with grizzly/Eurasian brown bear heads who are known for attacking. They come in brown, green, and a lighter green. 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 or a Eurasian brown bear.

An exceptionally violent and vicious animal, the sea bear took an immediate dislike to Squidward and attacked him repeatedly throughout the episode. The beast is attracted when Squidward, in mockery of SpongeBob and Patrick belief in its existence, performs everything that supposedly provoke the animal to violence leading the terrified duo to draw a dirt circle to deter the sea bear, apparently the only successful method of doing so. After teasing them when the sea bear does not appear, the animal shows itself and readjusts Squidward's sombrero to the position that serves to enrage it. The sea bear then violently mauls him and repeats this five times after for differing reasons: running, limping, crawling, and simple dislike for the cephalopod (twice).

Conceding, Squidward jumps in SpongeBob and Patrick's circle to escape the bear. The animal prepares for another attack when it notices the dirt circle. The circle actually proves effective when the sea bear, despite being easily capable of bypassing this incredulous defense, seems to be put off by it and grudgingly leaves after threatening Squidward with hostile gestures likely intending to attack him again when the chance arises.

Attracting a Sea Bear

There is a wide range of things that can attract a Sea Bear and why.

  • Playing the clarinet badly (the sound may agitate or upset them).
  • Waving your flashlight back and forth really fast (Patrick says flashlights are Sea Bears' natural prey, though the more logical explanation could be due to them favoring bioluminescent animals as prey and thus mistaking a flashlight for one).
  • Eating or holding cubed cheese; sliced cheese is safe (Sea Bears may see the cubed cheese as Bon appetite, though they would lose the interest in the cheese should it be sliced).
  • Stomping around (SpongeBob said that they take it as a challenge).
  • Wearing a hoop skirt (it might disgust them).
  • Wearing clown shoes (ridicule that makes the Sea Bear feel disgusted).
  • Wearing a sombrero in a goofy fashion (such as upside down or tilted, but in either way would likely be offensive to them).
  • Screeching like a chimpanzee (may mimic the sound of a dying animal or taunting the sea bear, but in either way, it is an especially big attractor with how SpongeBob and Patrick emphasize "never").
  • Running from a Sea Bear (might show cowardliness that would provoke them to attack you again if they mauled you once).
  • Limping from a Sea Bear (might also show cowardliness that is worse than running).
  • Crawling away from a Sea Bear (might also show cowardliness that provokes them to brutally maul you more than either when running or limping).
  • Simple dislike for the victim (likely only if you continue to do stuff that attracts them like Squidward did).
  • Possibly drawing an oval or circle in the dirt (possible attractor; the Sea Bear either attacked out of dislike again, or was attracted by Squidward trying to draw a circle only for it to be an oval, which does not work).


Sea Bears are very treacherous, aggressive, and merciless animals that won't hesitate to maul or kill their prey, be it due to merely for hunting or the said prey's provocative behavior such as stomping or disobeying other warnings above. At first, it attacked Squidward for his provocative behavior out of ridiculing its kind's existence by disobeying SpongeBob and Patrick's warnings, but it eventually mauled him several times for attempting to flee. However, they're not evil nor entirely hostile animals, given that one of them antagonized Squidward due to the latter ignoring SpongeBob and Patrick's warnings; it can be deduced that Sea Bears are actually territorial animals that are cautious with anyone who dares to enter their territory and won't antagonize nor kill them unless they displayed provocative behavior.

In spite of their aggressive behavior, it is implied that the Sea Bears won't intrude another animal's territory just to chase the instigator of the attack and would begrudgingly have him/her spared, which explains why they won't pass the Anti-Sea Bear circle.

In the Indonesian dub, SpongeBob said that Sea Bears would haunt campers, including even those whom merely camped near their home, implying that sea bears are attracted by campers who wander off to fishes' population, and the rule not to provoke them also apply as much as in their territory.


The only known thing that can prevent a sea bear attack is an Anti-Sea Bear circle (only a circle, not an oval, it has to be a circle). All the experts say it's the only thing that can stop a sea bear. It is also revealed that the sea bears are natural enemies with the Sea Rhinoceros (which are far more dangerous and can be attracted by the sound of a sea bear attack). The sea bears can also being prevented with tummy tickles and jellyfish jelly, and they seem to love them.


Though it is 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 (voice of Mickey Mouse from 1947 to 1977), 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

SpongeBob SquarePants

"The Camping Episode"

A sea bear is the main antagonist of this episode (although only being shown near the end).

Squidward initially 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. Squidward is mauled six times until he finally jumps into the dirt circle with the duo.

The sea bear appears again at the end, but seeing Squidward is now protected makes the sea bear leave the area, thus saving Squidward. The sound of a sea bear attack also attracts sea rhinoceros.
