The Krusty Dog is a food item sold at the Krusty Krab, and it only appeared in the episode: Krusty Dogs. It was created by SpongeBob SquarePants when he was playing with the Krabby Patty meat, and he shaped it into a hot dog.. Mr. Krabs then sold it at the Krusty Krab, replacing the Krabby Patty. As it is merely Krabby Patty meat with a different form, it tastes just like a Krabby Patty (without the ingredients excluding the ketchup and mustard). SpongeBob and Squidward later team up to get rid of the Krusty Dog for separate reasons (Spongebob because Mr. Krabs had removed the Krabby Patty from the menu and renamed the restaurant "Krusty Dog" since the Krusty Dog was more popular and worth more, Squidward because he was required to do extra work advertising the Krusty Dog) and do so by making it look like Krusty Dogs explode. After its discontinuation, Krusty Dogs were never shown again.
