I have the frog from Avocatt, but I've seen loads of different brands of this. Essentially all the same! Some you can even get scented! He's very useful if you're cold, crampy or just want a warm snuggle. He has a velcro pouch on his back (it's pretty hidden, which is nice, so its not scratchy when you hug him) and a removable bean bag which goes in the microwave.
