Mrs. Puff's House is a large pink house in which Mrs. Puff lives. Known rooms in her house are the kitchen, living room, bedroom, and a bathroom.
The exterior of the house is pink with three foghorns coming out of the sides and the top. Surrounding the house area is a white picket fence. There is also a tree and green grass. There are also bits of yellow on her house and there still is the average door and a window.
The kitchen is fairly modern, with tables, chairs, and bench tops. There is a fridge with a note on it, and there is also a small toaster. The floor is checkered and under the bench tops, there are cupboards for storing things. There is also a vase and a light hanging from the top of the blue wall. There are also windows and curtains. The kitchen only appeared in the episode "Pranks a Lot."
Just like the outside, the walls are pink and there are paintings. There is a TV, a plant hanging from the bottom of the wall, a fountain, and a window. A bookcase is also there and you can also see other random things there like a table with a flower. There is also a picture of Mrs. Puff shocked in the background, just as she is at the moment in the episode "No Free Rides." This picture also has an identical picture in the same spot, thus creating a recursive image. This same instance, in the same room, occurs in "Bumper to Bumper."
This is where Mrs. Puff sleeps at night. This room has a big bed. It is located upstairs. The bedroom appeared in the episode "Growth Spout."
This room has never appeared in the series, but the door to it is shown in "No Free Rides."
(In this episode, the whole kitchen is seen. Mrs. Puff is eating her favorite kind of cake until SpongeBob and Patrick scare her and she destroys the chair and table and finally landing on the table that she destroyed)
Her house is completely surrounded by a fence. It is revealed that Mrs. Puff keeps a garden in her front yard. The garden was thought by Mr. Krabs to be full of peanut plants, but they are actually peanut worms, and Mrs. Puff's pets.
After Mrs. Puff gets scared by the baby spotted glistening meadow worms, she bloats up, getting stuck in the doorway, the house then explodes. This is currently the only event in which Mrs. Puff destroyed her house because of herself.
