Gloomhaven is awesome, but...let's replace the cardboard chits with something more interesting, right?
I found a lovely rat from dutchmogul under the Share Alike-Creative Commons-Non Commercial license, and repurposed it. I chopped off the base, shrunk the rat, multiplied them, and mounted them to a 33mm Gloomhaven standee base that I had remixed.
I only built a "keyfit" base for this one...basically line up the front with the "X" on the dial. If they don't work, use a drill bit or round file to make the whole a little larger on the rat stand portion.
Support for the rat jaws.
