Wrestle Camp is a place that is mentioned in the episode "Krusty Krushers." It's a place where anyone can practice wrestling.
Although the camp itself hasn't been seen in the show yet, the poster and advertisement of it that has appeared in the episode show a yellow building that is shaped as two arms
with two navy blue doors, and glass windows all around the building. There is a red "W" on the building with a yellow flag. The building could be the location where wrestle camp possibly takes place in.
It was mentioned and advertised in "Krusty Krushers." This was one of the two choices for a prize; the other was one million dollars. Since Patrick and SpongeBob won the championship by defeating the champion duo, they were given the chance to go to wrestle camp and accepted, although Mr. Krabs wanted the million dollars instead.
