Here's the finished fox puzzle! I used linseed oil as the finish to bring out the color and grain of the blood wood and finished it off with a coat of finishing wax.

I'm quite pleased with how this turned out. : ) I'm sure you can see in the pic. Here, http://www.furaffinity.net/view/5256433 is the WIP pic to show it taken apart and it does come smoothly apart and back together. I wouldn't recommend for children as it can break but with care I'm pretty sure it's decently durable. Don't misunderstand and drop it off the counter though... It is wood, but it's a hardwood and the grain is the way it is to provide strength to the nubs.

The piece in this picture was up for auction at Anthrocon 2011. Congratulations to the owner of this one. I love the look the Blood wood gives the puzzle.
