Another good strip (The Scorpion and the Frog). I love the look on Scratch's face in panel 3, it matches the manic intensity of the moment, and the joke even works.
A couple things distracted me though:
1. I don't understand what's happening with Scratch's leg in panel 3. It looks like it's vibrating, foreshadowing claws coming out in panel 4 -- which they did, but with little fanfare. I would have expected some motion lines on the claws in panel four, accompanied by a "knives out" sound effect. ("sshhiiNGG!!")
2. Why do the claws look like that? Is it because they're turned toward the camera, so the points fall within the silhouette? They ought to be drawn so we can see their sharpy goodness, especially since they are the whole impetus for the joke.
