Oh boy...Shecky. Well, I guess he's necessary for this plot. Let's hope his visit is a short one.
So, Shecky is sort of a hobbit sized Troll, probably a little taller then Scratch. Presuming that whatever bar he's at is normal sized, shouldn't Scratch have trouble tapping him on the shoulder? Either there should be an arm extending from the bottom of panel three to tap "up", or there should be a speech bubble coming from below, with Scratch getting Shecky's attention.
How does Scratch know Shecky's full name anyway? Have these two even met before? How the hell did Scratch track Shecky down? And what's the barman's reaction to a midget Troll getting decked by an upright walking, talking cat with goggles and a ray gun?
Edit: I'm mostly being facetious with that last sentence.
