Let it go. And go. And go.

Don't be fooled by the dinosaur onesie, this little boy is all about Frozen. So much so, that it looks like his parents may have given the doll that sings 'Let it Go' to the wrong kid. Because he can't get enough of it. The problem for him is that the doll only sings for a few seconds at a time when the blue button is pushed, which allows his sister to control him like a dancing puppet. While the doll is singing, life is good. When the music stops, he goes into a deep funk that can only be lifted by another round of 'Let it Go.'
