A while ago I was reflecting on how to make a vertebrate animal with only one hind leg and sketched a page of various kinds of anatomical abominations, including this little guy above. Though the one foot aspect wasn't going terribly well, I liked the design and wanted to play with it a bit.
Roughly at the same time I put my hands on some Super Sculpey. (I've been wanting to try that out for ages. ) And the result is the other little guy above. Fun times.
