Hulk (Transformable!)

Yes, yes, you may just think this is another Hulk skin, nothing special here, and I don't want it whatsoever, but WAIT, ladies and gentlemen, for this skin is actually a Bruce Banner skin wrapped in hat layers!

OK, for those who didn't understand that, if you're playing in Minecraft 1.8 or higher, you can toggle all of the hat layers on and off to transform hulk from Bruce Banner to Hulk, and vice versa!

Once you take the skin, open MInecraft and go to a world. Press escape and go to your options, then "Skin Customization."
If all of the layers (except cape, that doesn't matter) are toggled to ON, you will be Hulk, and OFF will be Bruce Banner.

Have fun kiddies! :D
