There's probably three ways you could go with a mini for the Soft Master. One would be in his orange kimono from the comic flashbacks. Two would be the brown suit he wears when infiltrating Springfield.
Or, you could do him in his Cuban-Chinese Restaurant outfit as he was introduced in the comic:
I used a Reaper Miniatures Bones Innkeeper and used green stuff to make his pants look more like modern trousers.
Now, I just need to make a miniature Cuban-Chinese Restaurant (with ninja bolthole.)
