bd2-p but with butterflies instead of \\\! :d  
  
btw do butterflies use the same graphics as diamonds which are cut in two halves and put together the other way? :d

actually, when it comes to the simplistics, it appears the sprite indeed is the first frame diamond shifted four pixels horizontally, and the butterfly's frames were modified for the "flutter" using this initial pose.  
  
(remember, the screen resolution used in c64 boulder dash is actually 160x200, so the pixels are stretched 2x horizontally!)

the butterflies themselves are their own animated element, however, one that is easily revealed in the dumpster fire that is bd3, when the butterflies were replaced with eyeballs.
