"Hand-y toys"

I love kids' imaginations!   Somewhere around Christmas time, I noticed Kayla talking with her hands.   Not as in Sign Language, but using her hands as puppets.   She had them talking to each other.   I asked, and she said the right one is Mary and the left is Joe!    They have full conversations with each other, which are usually pretty funny.   No toys around?   Hands are always available!
