An advertisement for free interest from the bank broadcasts on the Krusty Krab's TV. Mr. Krabs hears about it and leaves SpongeBob SquarePants in charge of the Krusty Krab as he rushes to the bank. Mr. Krabs notices that people get interest. He over-obsesses about money, and Nancy presses a button for guards to kick him out. Mr. Krabs disguises as a mustachioed man, but the disguise fails.
Mr. Krabs disguises again, but as a woman, and Nancy told him he had to make a deposit. Mr. Krabs chooses to deposit only a penny but is anguished. While saying goodbye to his penny, he falls down to a room full of money. He arranges this pile of money into a restaurant. SpongeBob sees that Mr. Krabs is gone. He goes to Pearl, then he calls Mr. Krabs, who says he is running out of oxygen. He then goes to Patrick and asks for his help to break in a bank. Patrick does a spit-take and is shocked at how crazy this is, only to say it is great. SpongeBob and Patrick arrive at the bank and discuss how to get it. Patrick brings some shoelaces, and SpongeBob grapples them to the roof. The shoelaces untie themselves, and he falls. Patrick brings a grappling hook, but it also fails after they took the vent that led that back at the front. He has a key, and SpongeBob commands him to use finesse. Patrick uses his "finesse," but the bank opens at the same time, causing Patrick to run off. Mr. Krabs hallucinates and imagines himself on a beach with a woman made of money, only for the beach to be on fire. The money is the sucked by a vacuum cleaner, which is a dragon in Mr. Krabs' imagination. SpongeBob breaks in but takes his ski mask off. He requests a bank guard to withdraw one Mr. Krabs. The guard sees Mr. Krabs breaking the vacuum cleaner, and promptly kicks him out with SpongeBob, along with his "deposit." Mr. Krabs is angry that the bank didn't even give him his free interest, but gets another penny thrown at him, then says he doubled his money.

- This episode was released on iTunes on May 25, 2013.
- This episode is available on the Bikini Bottom's Most Wanted, Complete Ninth Season, and Next 100 Episodes DVDs.
- This episode premiered in Canada on March 12, 2016, three years after it premiered in the United States, marking the longest gap to date between any USA and Canada premiere of a new episode. Episodes usually premiere in Canada a few weeks to months after they premiere in the United States.
- Although this episode premiered in 2013, it was produced in 2012 according to the credits.
- This was the final episode to credit Derek Iversen as a writer for the show, as he was promoted to animation writer in 2015.
- This is the first appearance of the Bank of Bikini Bottom Bank.
- This is the second episode to show Nancy Suzy Fish working as a bank teller. The first is "Mermaid Man and Barnacle Boy III."
- This is the second episode where SpongeBob and Patrick attempt to break into a place. The first is "Doing Time."
- This is the second episode where Mr. Krabs dresses as a woman to get to money. The first is "The Cent of Money." In fact, the outfit he wears is similar if not the identical to the one he wears in that episode.
- This is the third episode where figures on monetary objects have been able to perform fish-like activities. The first is "Money Talks," and the second is "Welcome to the Bikini Bottom Triangle."
- This episode preceded the series premiere of the Nickelodeon animated series Sanjay and Craig.
- The bank manager has a similar personality and voice to the Bikini Bottom Mint tour guide, Bill. They both seem to have calm voices even when angered. Ironically, both of them work in similar lines of occupation.
- The vacuum cleaner seen in this episode is similar to Squidward's vacuum cleaner from "Squid's Visit."
- Although Nat Peterson is seen as one of the officers that escorts Mr. Krabs out of the bank, he is later seen at night in the Krusty Krab, out of uniform, eating a Krabby Patty.
- Usually, in order to open a safe deposit box, one must have two keys: their own and the bank's. Nancy Suzy Fish only uses one key and is never shown giving Mr. Krabs a key.
- When SpongeBob asks Patrick about having shoelaces, he says that it was the closest to him of having shoes. However, he wears shoes in "Your Shoe's Untied," which means that this episode takes place before that one.
- In the Hebrew version of this episode, there were originally no words in the title card. However, it was later fixed.
- This episode premiered six years after Nicktoons: Battle for Volcano Island was released in Europe and four years after SpongeBob StarPants was released.
- Mr. Krabs runs out of oxygen while in the safe, despite the fact that it is underwater and nobody breathes oxygen.
- This episode's title is a pun of "safe deposit box."
- The "double the money" promotion in this episode is similar to what credit card companies do to advertise their credit cards and get customers who use them.
- When Mr. Krabs runs out of the Krusty Krab to get to the Bank of Bikini Bottom Bank, in that shot, the road that leads to the Chum Bucket is not there. The Chum Bucket itself isn't even there.
- When SpongeBob and Patrick are at the door and Patrick attempts to pick open the locks of the bank doors, the horizon is still night dark. Yet when the bank manager changes the "Closed" sign to "Open" and opens the doors, it immediately turns to morning.
- The bank manager knows SpongeBob's last name despite never having been told it.
