Simply great to hand over to birds as they are. Most enjoy picking out all the many pieces of colourful crinkle paper then munching away at the ball itself. Your customer can use these as the basis for creating a new toy every time! Remove the crinkled paper, stuff the munch ball with various treats and replace the paper to hide what`s inside. Parrots love searching for things especially if there is a tasty reward at the end of it!
