iFetch Frenzy BRAIN GAME: The iFetch Frenzy is not a launcher; its a game. Your pup drops the ball into the top and scrambles to find it as it randomly rolls (6-12 feet) out of 1 of 3 chutes at the base. MINI TENNIS BALLS: Comes with 3 non-abrasive miniature tennis balls (1.6 diameter) and a hidden ball storage compartment on the bottom.
