Foraging foot toy for all sized birds. On the outside it has a stainless steel wing nut and bolt through the center with beads to spin. Your bird has to undo the wing nut, pull out the bolt, open the wood box, and get the treat out. Or, they can chew through the box like my moluccan does, and they are left with a bolt and wing nut to play with. Lot's of fun in this little toy. Will come with either pine nuts or nutriberries.
