Megafauna - Hippo and Mice

I'm finally picking up the Megafauna series again, after spending some time on 3D and working ahead on the comic. I knew I wanted to do a massive hippo ass. And I'd thought about doing mice and elephants together, but that seemed a little cliched (and I've done it several times before already). But combining the hippo and the mice seemed to work out pretty well! 

This one has quite a number of alts, including the hippo by itself, and the hippo plus mice in various positions.
