I think Babies R Us had them! I remember saying to my husband how cute the monster stuff was and I'm almost positive they had a hat--if not that exact one, something very similar.
Buy the set. Its cute. I bet they have it at Kohls for under $10.00. It wouldn't be worth my time trying to hunt down the little hat on its own just to save a few bucks.
Re: XP: Where can I get this hat?
Yes, we want JUST the hat from the set I linked from Amazon.
I'll check BRU....
You could easily take the stitching out to remove the "Aunties little monster" thing. Also it's pretty small and cant really see it well.
