I wish I'd been able to get the blood dripping from Floyd's ravenous mouth to look a little nicer, but if I had any artistic ability, I wouldn't be using clip art on a website to make these comics.
Anyway, enjoy Floyd while he's here, because this character won't be lasting much longer. Hey, it's called Ninja and Dave. If it was called Ninja and Dave and Floyd, then it would make sense to keep him in the strips. It would also make the title grammatically incorrect.
And yes, those "ninja school" tags will make more sense soon.
