A bottle of pills found in the Kitchen drawers of the Pink House. Using the pill bottle will cause a dizzy effect for the player, making the prompt button spin and the screen twist with the effect intensifying as the player takes more. It takes eight pills to make the player throw-up and nine to die, leaving behind a splatter of blood and a poop.
The pill bottle is the best method for getting the Skull chest brand when Summoning the Demon.
