Treestache Bundle

 is a limited-time premium consumable that was released on October 3, 2018, as part of the Treehouse of Horror XXIX Event. It was a possible prize in the Magical Mystery Box (2018).

It contains:
 * Treestache's Grove
 * Treestache
 * Magic Act Milhouse

If the player already owns Magic Act Milhouse, as it was a free costume obtained as part of the ThoH XXVIII Act 1 main questline Angelica Button and the Mystical Beasts, only Treestache's Grove with Treestache becomes the alternative prize in the mystery box.
