A Hole in the Ground
The Hole in the Ground was introduced in The Sims Makin' Magic. Sims can jump in the Hole to go to Magic Town, or to go from one Magic Town lot to another. Sims do not have to have magic to use the Holes, and children can use them to go to Magic Town on their own.
The Mystery Man's package contains a Hole in the Ground, and it can also be bought in Buy mode.
If the Tragic Clown is trapped in a room, he will use a Hole in the Ground to teleport to the player's Sims.
