At Flipo, we believe laughing is contagious! Once our motion-activated Crazy Critters start laughing, you can't help but join them. Flipo created Crazy Critters from soft yet durable materials. Simply pull apart the hook and loop closed pocket on the underside to reveal the Crazy Critters battery compartment and main power switch. Flipo also created a more easily accessible on/off switch located on the left paw of each Crazy Critter. Give the paw a squeeze and you'll be greeted by your Crazy Critter, squeeze it again to turn it off. The Flipo Crazy Critters are a perfect pick-me-up gift for all ages! Each Flipo Crazy Critter requires 3 AA batteries (not included).
