456 Snuffle Circle

456 Snuffle Circle is the address for Snuffleupagus' cave, where Snuffy lives with his mother, father and sister Alice. The address is given in the 1989 book Bert and the Magic Lamp.

The interior is a cross between a dank cave and a cozy suburban home. The walls are bare stone, but the living room has comfortable chairs and a fireplace. The ceiling of the cave is covered in green moss, which the Snuffleupaguses like to pick off as a snack. Their kitchen is outfitted with a stove. A stream runs through one part of the cave, where the family bathes.

The cave is connected by tunnels to other caves in the neighborhood, including the home of Aunt Agnes Snuffleupagus. Another tunnel leads to the home of the Count's bats.
