Wacky Bucks look like the US dollar. The only differences are that Mr. Krabs is on them as the President, the Krusty Krab is in the background, they say "Not Legal Tender" at the bottom, have their name written on them, and have clams on them. They also have the number one on all corners.
Role in episode
When SpongeBob gives Pearl some money, she points out that the Wacky Bucks are not real currency. SpongeBob states to her that it is the money Mr. Krabs pays him with.
- In real life, it is illegal for one to pay their employees with fake money.
- The numbers on the bottom of the bills read "01123581321(...)." This is the start of the Fibonacci sequence, a sequence in which the next number in the sequence is the sum of the previous two.
- In spite of Mr. Krabs paying SpongeBob with these, they do not appear in any other episodes.
