Item description:

Mad Hatter Trophy!
I've made this game save to save some time on collecting all 25 hats. It is a "blank profile save" so you will have to resign the save with your profile. This save might unlock some other "trophies" as I have not tested it on another account, so if somebody could try it out and tell me the trophies that unlock while loading the game that would be great. I have finished this game at 100% since it is about the most easiest trophies ever.

the only hat missing is the "Paper Bag Hat". Which can be obtained via "Stage Select".
"Act 4 - Anger Management"
As soon as this chapter begins, run to the far left corner of the map this is where you should find the paper bag hat.
