Who lives in a pineapple under the sea?
(SpongeBob Squarepants!)

Gary was adopted by SpongeBob at the local animal shelter.

Bikini Bottom, SpongeBob's fictional home, is based on an actual place in the Pacific Ocean.

The Krusty Krab is the most popular restaurant in Bikini Bottom. It has two employees: SpongeBob SquarePants and Squidward Tentacles.

Squidward's skill with the clarinet is generally portrayed as sub-par. In "Sweet and Sour Squid," his disastrous attempts at music create a mass noise disturbance that requires the intervention of the authorities. However, he plays well enough in "Hello Bikini Bottom!" for a musical manager to offer him a job.

Gary meows like a cat.

Sheldon J. Plankton despises Mr. Krabs for running a successful restaurant because his own business rarely gets any customers.

Sandy Cheeks is a squirrel from Texas who lives in an air-filled glass dome and wears a diving suit to breathe underwater.

Despite being a senior citizen, Barnacle Boy is still treated like a child by his mentor.

Unlike most of the other main characters, Patrick lacks a nose. However, in "The Battle of Bikini Bottom," he is able to grow a nose through sheer force of will.
