In-game Footage[]



  • Bozo has been added in Booster Pack #1, after the initial release of the DLC.
  • Bozo is based on this Steam Workshop item by electoon.
  • This item is a reference to Bozo the Clown, a clown character whose broad popularity peaked in the 1960s.
  • The item's ability to inflict fear may be a reference to coulrophobia, the fear of clowns.
  • If you die with Red Heart containers and enemies destroy the rainbow poop in time, your hearts will fill up again, still leaving you dead.
  • Added in Repentance Aries Aries, Bozo, and Yuck Heart Yuck Heart are the only 3 items that have both the 'nolostbr' and 'offensive' tags, meaning The Lost The Lost can't find them if Birthright Birthright is obtained, while Tainted Lost Tainted Lost can always find them.
