This is a model of Twilight Sparkle's Treehouse Library that should be just the right size for the Blindbag ponies. It comes with 5 different pieces; the base, the roof, the door, and the two parts of the house itself. I made it this way so that it can be opened up and played with in a variety of ways. Additionally there is a hole in the door and next to the doorway of the house so that the door can be made to have a hinge with a bit of string.
