Hand/Electronic Cozy Warm Pocket Thing

This little monster looks like his eating whatever you put inside
So I get to go to makers faire every year with my family in san jose and it's always amazing. But one of my first years attending the faire, I signed up for a sewing tutorial where they provided us with the fabric and sewing machines and showed us step by step how to make the cute little monster. He has an inner lining (that if you pull out looks kinda like his barfing :P). But he was fun to make and really cute. They said it was for keeping your phone inside, though I didn't see a need for that so now I carry it around and use it to keep my hands warm.
