Get rid of those damn teeth and replace them with 4 medium beaters. Use the rest of the weight on stuff.
There's really no room, any further in and the drive motors (mags) won't go because of the perm.
That thing is adorable and I want to keep a colony of them in a small lexan box in my garage.I'd go for a slightly higher resolution skin, 512x512 might give it a cleaner look overall, rather than the lossy pixeled look it's got at the moment. Exposed Piglet isn't that appealing either, though I'm not sure how a Flipper Segment housing would look.
