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.
- He is voiced by Tom Kenny.
- SpongeBob, Patrick and the gang made their first guest appearances in Kids World's Adventures Series.
