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)
