The Art Museum is, as the name says, a museum with art things in Bikini Bottom. It just appears in the episode Squidward’s School for Grown-Ups. Squidward visits it with his new best friend, Patrick. SpongeBob comes along without Squidward and Patrick knowing, because he wants to win Patrick back as his best friend. The only employees known are two security fish.
The Art Museum has a big solid wall of metal on each side. Infront it has a block wall and a stairs which leads to a brown door. On the top, it says „Art Museum“ in grey letters.
