Wigwam

The wigwam's are an imaginary species. They look like the shadow of whatever disfigured animal the person discussing it chooses it to look like, and they can talk like humans. Wigwams can take any disfigured animal form, it all depends on the imagination of the person talking about them. They are a mischievous species, that take the blame for all the shenanigans of the referencing human.
