Wacky Bucks are a made-up form of currency that Eugene H. Krabs pays SpongeBob whenever he feels cheap or cannot afford to pay SpongeBob his weekly paycheck. They have only appeared in "One Coarse Meal."
One time, when SpongeBob gave Mr. Krabs' daughter Pearl some money, Pearl said, "Hey, this isn't real money," prompting SpongeBob to reply, "But this is what Mr. Krabs pays me with: Mr. Krabs' Wacky Bucks." Stunned, Mr. Krabs said, "Hmmm, the boy is catching up to me."
