Angry slugs fighting each other. Hehe... their amo is salt. Don't do that to a real slug though, that's just torturous. Just imagine your body being incinerated by a single grain of salt and your flesh crinkling into dry dust as the moisture from your skin evaporates. Slowly the pain creeps of your body as you convulse helplessly... well anyways. In real life this is not all fine and dandy.
I also used a new shading technique (only for certain cartoons) with my epic horse pen. I know right, it's so awesome. I got it from cracker barrel.
