We've come up with two edits of the Duck Mouse video: first, a short guts-free trailer to pique your interest, then a more complete view of all the taxidermy action.

The longer version, including a bit of dissection:
Step 1: Obtain and dry duck feet
If you or your friends hunt or raise ducks, you're all set. Otherwise you could visit your local asian grocery, butcher shop, or live poultry source and ask for the leftovers. These feet came from a green-winged teal I shot myself. I ate the rest of the bird (VERY good) and saved the wings in my chest freezer for a future project.
Cut the feet off just at the bottom of the feathers, and wash them in nice soapy water. The webbed feet will fold up if you let them, so spread out the webbing and pin them on a piece of cardboard to dry. You'll need two pins to keep the toes spread, and a couple of pins to prop the leg in an upright position. Try to make as few holes in the feet as possible.
I left mine on the mantel to dry, and just forgot about them for a couple of days. If you're in an excessively humid area, it may be necessary to put them in an oven set to "keep warm" to dry them out. They'll be stiff and a bit crispy when dry, so handle gently.
