Mrs. Puff's vegetable garden is an area that appears in the episode "Growth Spout."
The garden is quite small, containing very few vegetables. Small plants of certain vegetables are planted and spread out, leaving most of the area blank with just grass. There are not many vegetables in this garden, which is surprising considering the vegetable garden is very important for Mrs. Puff, because she even talks about it in her sleep. It is located at the front of Mrs. Puff's House.
In "Growth Spout," Mr. Krabs looks for food for Pearl, who is going through her growth spurt. Krabs then steals food from Mrs. Puff. He spots a lot of peanuts, but it turns out that they are Peanut Worms. The worms squirt gooey liquid in his face.
