Even if it was predictable it was enjoyable. I think you mentioned in one response that you're thinking about doing or not some more about the other bunnies, something you could do is the same "happy tree friends" or "joe cartoons" did. The clue in them, I guess, is the way the bloody things occurs and how they develop. We all know something messy will be going on when we watch them, but, for example, how much pain will the character(s) endure before dying or some other gag to come is what matters.
Another idea would be doing a semi unexpected "contraTwist", like "Spy Vs Spy"; you know the bunny is going mad and become a monster, but perhaps even so the sheep without transforming beats the crap out of him or kicks him in the balls and scapes with the food. Like DR House intros where you think A character will be the one getting sick and its always B.
That reminds me of a movie where this young man was bullied by another guy, so he exercises and gets strong, but he was still a victim and a coward in his mind, so when this big and strong man faces the second, and the second after being scared at first, knows that the big-one is still scared of him, the little and skinny bully continues beating the big poor brute. It's just kind of pathetic, sad and hillarious : p
