I baffled my family and friends with secret quacking, I made them laugh, we had quack battles (both parties won!), we mildly confused the cats, I tap them as I pass by for a quick giggle, etc, etc.....
I love that they're USB-rechargeable, they're physically satisfying to use (I also have the lovely four-key sensory doodad and the frogs!), they're the best product I've purchased from you guys-- and there have been quite a few.
Thank you many times!
