Yada yada yada...
This replaces Id's cool and scary fiend with a funny looking
dirty bipedal ratlike creature.
Feel free to use it as you like.

qc.:    no (use fiend's)

Feel free to modify the sounds or skin to fit this to your project or whatever.
I think it might look better with a reptilian skin and no ears.  Maybe holding a big gun.
