A creature "has a hat" if the creature depicted in the art is in possession of a hat. That creature doesn't need to be wearing the hat. A background character such as a scale bird having a hat won't count.

A hat is a garment worn on the head that's not part of another garment. Hoodies, for example, are not hats. Items that cover only the face and not the top of the head, such as a face mask, are also not hats. Hats are purposely decorative. Simply balancing a thing on your head doesn't make that thing a hat.

The above information pertaining to hats for creatures also pertains to actual hats for players.

Wigs and headbands count as hats. There are wig and headband stickers.
