At Flipo we believe laughing is contagious! Once our motion-activated Crazy Critters start laughing, you can't help but join them. Simply pull apart the hook and loop closed pocket on the underside to reveal the Crazy Critters battery compartment and main power switch. Give the paw a squeeze and you'll be greeted by your Crazy Critter, squeeze it again to turn it off. There are 3 different Crazy Critters to choose from, collect them all, and have a ball! The Flipo Crazy Critters are a perfect pick-me-up gift for all ages! Each Flipo Crazy Critter requires 3 AA batteries (not included).
