Dream Mr. Krabs, also known as, "Daydream Mr. Krabs," is the dream version of Mr. Krabs, who first appears in the episode "Sleepy Time."
Dream Mr. Krabs' appearance and description is exactly similar to Mr. Krabs.
He is trying to catch the Moby Dollar at his Dream Ocean. When SpongeBob comes to his dream, Mr. Krabs tells him to take his big wallet and put the Moby Dollar, that he caught, inside it. However, SpongeBob accidentally lets the wallet fall into the sea and Mr. Krabs ties him up with a rope tied to a plunger sticking out of a gun and fires it.
Shubie asks to watch King Neptune eat during his party, which is being held at the Krusty Krab. At first, Mr. Krabs finds it weird and wonders why he would let her do that, but Daydream Mr. Krabs appears with a hammer with a dollar sign on it and wacks Mr. Krabs with it, indicating that he can make money off the opportunity.
