Wild Frontier has (had?) a batty character called Victor.
Here is his first appearance. In addition to later appearances in the strip (he's got a cute tail by the way), there is also a sketch of him and some other crew members in the Concept Art department, but nothing on the Characters or Fan Art pages, but hat's just because they are empty.
As for snakes,
Vinci & Arty went to a yoga class in October (well, Vin and some friends did), and one of the other participants turned out to be a garter snake. With arms, no less. Bennie didn't exactly make a good
first impression...
