A giant Bony Beetle which will walk around and stay on ledges if the extra bit is set. If Mario jumps on it, he will simply bounce off. He must spin-jump on it to dismantle it. It is invulnerable to any damage.
Converted to PIXI and added SA-1 compatibility. The code and comments have been left mostly untouched - after all, we need at least one dahnamics sprite with its idiotic code preserved. Added a screenshot and tags.
A nice sprite which could be useful for some castles or maybe even puzzles. It consumes a fair amount of graphics space, however, so it might not be very useable with other castle sprites.
