Get the best of both worlds! All the fun of a babble ball combined with the toughness of the X tire! The small ball is 8.89 cm across and makes more than 20 realistic animal sounds (lion, frog, coyote, dog, pigs, horse, rooster, elephant, cow, goat, cat, and a variety of birds.) The sounds are activated by touch, and turn off automatically. The batteries can be replaced when they eventually run out. Dogs can't get enough of this toy!
