SpongeBob is 33 years old and lives with his pet snail, Gary. HIs best friends are Patrick and Squidward. Spongebob spends his weekdays working at the Krusty Krab and likes to go jellyfishing in his free time. While SpongeBob has an optimistic demeanor, he still has a breaking point and can snap when pushed beyond his limit.
Physical: SpongeBob walks to work every morning (around 3-5 miles) and practices karate with Sandy on a regular basis.
Intellectual:SpongeBob has a giant library in the basement of his home, so we can assume that he reads a significant amount of books, despite his naive nature.
Emotional:SpongeBob feels a sense of worth when interacting with customers (and just people in general). He's glad that his food is able to cheer people up. This is why SpongeBob is able to maintain a positive outlook on life.
Social:SpongeBob talks to Patrick and Squidward on a daily basis and likes to go jellyfishing together. He also socializes with the citizens of Bikini Bottom and is generally liked by most.
Financial:SpongeBob's living situation is great, so we can assume that he has an adequate salary as a fry cook at the Krusty Krab.
