Snoopy
Snoopy's house looks small from the outside, but the inside is much bigger, like the Tardis from Doctor Who.  He has many things in his house, including a TV set, Van Gogh painting, pool table, cedar closet, and many other things.  It has been destroyed multiple times, including being burnt down, destroyed by a falling icicle, and being smashed by the violent cat who lives next door.
