Mr. Krabs' Pirate Ship was a Pirate Ship. It appeared in a Flashback in the episode, Grandpappy the Pirate. Mr. Krabs sold the Ship and Fired his crew.
- In Grandpappy the Pirate, Mr. Krabs says that the Krusty Krab used to be a boat, and that it was always called the Krusty Krab, but in the Krusty Krab Training Video, he says that the Krusty Krab used to be a retirement home. This is a plothole.
