SpongeBob SquarePants is another one of Pooh's sea friends and a best friend of Patrick Star.

He lives in the UnderWater world of Bikini Bottom.

SpongeBob is a very clueless, immature, and hyperactive character with a happy-go-lucky personality and a heart of gold. He is an extremely determined person, and will often stop at nothing to accomplish a task, especially if its concerns his friends. He is also somewhat dramatic to the people who are kind to him, for example, to the mailfish. He is also very over-confident and tends to make a big deal of small problems, such as losing his name tag.
