This is actually a suggestion of outfits I thought of that I think would make a cool addition to the Transformice game..
I colored it really quick since I have to get to bed soon, so pay no attention to the scribble works. lol
As for The Hulk, I think a green mouse skin would be cool. And his shorts would be a neat addition.. xD
Cap's shield could be a neck accessory, buch like the umbrella, only it's being held on the side of the shoulder in the game.. or maybe on the side on the back?
Ironman... pretty much how it looks. It could be a head accessory.
Thor's hammer could be a mouth item, and the capes could be a neck accessory..
Loki's helmet can be a head accessory, too.
...I really love how I did Ironman mouse. XD
