The Bikini Bottom Convention Hall is a location that first appears in the episode "Shell of a Man." It serves as the main setting for the second half of the episode. It also makes a cameo in "Two Thumbs Down."
The exterior of the Bikini Bottom Convention Hall resembles a torpedo in the sand that is green in color. There is also a sign that says "Welcome Navy Buddies" on the front side.
The inside of the Convention Center has metallic walls and tables where the navy buddies can sit at to discuss their past actions. There is also a stage where they announced the winner of the manly toughness award.
Mr. Krabs and SpongeBob go here to meet up with Mr. Krabs' navy buddies again. However, Mr. Krabs molts his shell and is too ashamed to show himself in front of his navy buddies due to his weak body. Mr. Krabs then has SpongeBob go inside his shell and masquerade as himself. The plans are going well as SpongeBob manages to get Mr. Krabs' navy buddies to think he is "Armor Abs Krabs" until he is announced for the Manly Toughness Award. SpongeBob accidentally talks about blowing bubbles and Jellyfish Fields but, fortunately for him, the navy buddies still believe he is Mr. Krabs. However, when SpongeBob gives Torpedo Belly a "steely belly butt," the shell breaks and SpongeBob is revealed in front of everyone. Mr. Krabs then appears and reveals informs everyone about his condition. As Mr. Krabs is about to leave with SpongeBob, Mutton Chop hands over the Manly toughness award saying admitting that he molted his shell was the toughest thing he has ever seen. Then, the rest of Mr. Krabs' navy buddies all reveal their conditions and all share a laugh. Mr. Krabs then states to SpongeBob that his shell will grow back eventually.
