Mysterious Candy is a trinket added to The Binding of Isaac: Rebirth. It is, presumably, a milk chocolate bar made of twelve squares.
- Makes Isaac create Poop on the floor randomly. Also can produce a Bad Gas.
- Midas' Touch - Allows Isaac to randomly spawn Golden Poop.
- Judging from the "mysterious" aspect of the chocolate and its results, this item is presumably a laxative worked into chocolate form, such as those sold by the Ex-Lax company.
