This would be something that would occupy a 2' x 2' square, and open up to allow play inside as well.
We're struggling over what materials to use to build the base structure. We can't really use licensed toys because we may want to put this in a rule book that we will eventually sell, so we really need to start from scratch, or use kits that are long OOP and unrecognizable.
Any advice, links, help, is much appreciated!
Thanks!
