The outside of the Bank of Bikini Bottom Bank greatly resembles a giant white crate. It also has two doors with two windows on both doors. It has two columns and a sign that reads the bank's name at the top.
The inside of the bank resembles any other bank. There are four places where the customers can go and withdraw or deposit their money.
The bank also contains a large vault, a safe deposit box room, and an elaborate drain system which links to a Bikini Bottomite's house.

"Safe Deposit Krabs"
The Bank of Bikini Bottom Bank is first announced by Johnny Erain when he says that the mayor is talking about the grand opening. The mayor then tells that the first 100 customers that join the Bank will receive "instant interest," much to Mr. Krabs' delight.
However, when trying to get into the safe, Mr. Krabs ends up getting trapped in the bank overnight. SpongeBob and Patrick attempt to break into the bank with no success, but, eventually, Mr. Krabs is later released the following day.
