Phone Booth is a machine in Fiend Folio, a mod for The Binding of Isaac.

Will randomly start ringing, allowing Isaac to pick up the phone. While talking, Isaac is constrained to the Phone Booth and can move only a short distance away from it.

While on the phone, the background music is lowered and special audio plays occasionally.

Touching the machine again will hang up the phone, allowing it to ring randomly again.

Can only appear in one very rare Shop layout with a weight of 0.1, and has only a 1% chance to spawn inside it, as well as one I AM ERROR room layout with a weight of 0.01.

When destroyed, has a 20% chance to drop a Penny.
