The trailer is first seen in the woods in "Mirra Mirra On The Wall" when the twins discover it while searching for Mirra. It must have been abandoned a while ago because it had been completely overgrown when it was discovered, and was being guarded by some sort of monster.
The trailer is fairly beaten up on the outside, with a few dents, scratches and spots of rust, though the inside is in better condition. The front window has several cracks, one of which has been patched up with tape.
The inside of the trailer consists of one main room and a bathroom. There are two beds and a few other pieces of furniture inside.
