Also known as a Chuckle Buddie or Roffle Mate, walk past this cute little dog and the fun begins! Even if you can resist the infectious laughter, the way this cute stuffed animal dog rolls around and flops his tail will be sure to bring anyone a smile! Chuckle Buddies can sense movement, so just place Rollo the Laughing Dog on the floor and when someone comes walking along (or better yet, trips!), this plush dog will break out into hysterical laughter! Great for kids or adults. Operates on 3 AA Batteries.
