In-game Footage[]


  • The item is a reference to Humble Bundle, collections of games and soundtracks that are sold online through a "pay what you want" system. The original The Binding of Isaac was represented in three humble bundles.
  • This item displays as "Humbleing Bundle" when picked up as well as on the debug console. "Humbleing" is a common misspelling of the word "humbling", though it is unknown if this is an intentional typo or a mistake.
