I had a hard time coming up with a reasonable story around the bunny death. Then I found the biggest chocolate bunny I ever see on the free market... 1kg of chocolate bunny. That's 2.2 pounds of chocolate in one bunny. That thing is larger than most puppets I have. And that sparked the idea of "Chocolate Bunny Revenge". I added te collie because it looks very calm and non-destructive... also I wanted to use the new puppet ;)
The Coyote led to the anvil dropping. It's not that easy to drop an anvil in an intereting way IRL: they bounce!
