This is our clunkiest toy ? the toy with the biggest wooden blocks by far. This toy is so massive (and so heavy) that even our resident Blue and Gold Macaw, Sam ? who rips through any and every wood toy as if it were paper ? has taken weeks to make a significant dent in this toy. Everything on this toy is held together with heavy-duty metal chains, and because of the design of the toy it?s like seeing a whole new toy every time the toy is rotated. Turn the toy around each day to give your parrot a new angle to work at and this toy is sure to last. We recommend this toy for the BIG birds only (such as Greenwing Macaws and Hyacinth Macaws). Even a Moluccan Cockatoo might have trouble with this one!
