Life size is great. A male skull, as they tend to be bigger.

Hmm. Foam-filled latex is a no-no. So is anything that invovles glitter. Nothing that has a "powder-y" feel to it, really, or has something that hungry crix might nom on, then pass onto Bob when he eats them. Strong smells to the plastic or material are also bad, though those can be fixed with lots of soap and water. :3

omg ilu so much
