I have not seen any shadow costume.My son wanted to be him for Halloween also and searched everywhere.I am in the process of making one for my son.If you are crafty and patient and have the time it can be done.I have most of it done now,but working on the head piece now,which is what makes the costume.
Well, I found one at this store called Spookies. It's only available in the fall. It's really popular in the town of Chicago. THey have all kind of weird costumes. From Sonic, to Shrek, to a Angel. They have, like all costumes. Hope this helped!
