It's called My Little Cthulhu. You can get one [or several!]
here.
But wait, there's an alternative! They're called Mythos Buddies. They're blind boxed, which a six year old may love or hate equally. The price is pretty steep considering how small they are, but I assume she has small hands, so that might not be such a draw for her.
You can get them
here.
Edit: Okay, so I didn't do so well digging up links. The first is for a preorder, and I think the second is for wholesale. I'd dig a little more, but I have to get back to work. Sorry.
