The building resembles a Viking ship. Inside, it contains ancient artifacts and other relics, such as formerly the Atlantean amulet, which SpongeBob and Patrick completed to get a trip to the underwater city of Atlantis. Mr. Krabs took admission there (unofficially). Squidward was seen painting pictures that relate to Atlantis. It includes many artifacts, art, historical items, and many other things of ancient history.
Role in series
The customer being scammed is Miss Shell and SpongeBob finds Squidward almost immediately after they enter. There is also a whole scene that explains what Atlantis is.
SpongeBob's Atlantis SquarePantis
The third level of the game, called "Snap Happy!," is set at the Bikini Bottom Museum. In it, the player travels through the museum, taking photos of the various exhibits. "Snap Happy!"'s side-levels ("Fussy Photos!" and "Give Me a Break!") are also set here.
"Are You Happy Now?"
SpongeBob takes Squidward here to try to help him to have a best memory. Squidward finds a statue of his in the museum. He is happy, but soon, Fiasco burns the statue, which tarnishes Squidward's oppurtunity of having a happiest memory.
The museum was bigger than it is now, but Patrick sat on a mine and part of it got destroyed.
