The battery pack is located on the doll’s back. Remove the skirt and vest, bend the doll’s arms gently if needed. Unscrew the battery cover at the back with a Philips head screwdriver and replace. Be sure to dispose of batteries properly.
Try replacing batteries and make sure there are no cracks in the propellers. If there is a crack in the propeller, do not operate toy. If your cat is still not flying, please contact Mattel Consumer Services.
