Furnished Pineapple in a Can is a canned pineapple house that appears in the episode "Home Sweet Rubble."
It comes in a can with a picture of a pineapple on the front within a white circle outlined by dark red. The front also depicts a green square contained within a black border. The upper-left side of the can reads "Furnished!" in purple letters within a light yellow explosion banner.
When opened, a full-scale pineapple house pops out of the can, complete with furniture.
