My ultimate fantasy is to have an actor that is a crab with a launcher on its back, which in turn shoots out more identical crabs with launchers. in other words, they multiply exponentially. Doesn't need to have any weapons or anything, I just want the only danger to be getting crushed under an expanding wave of crabs. Obviously, this is going to need some lua magic, otherwise I'd do it myself. I could try and supply the art for it, if it helps (though you might need to tell me exactly what is needed). Thanks!

This one was a lot of fun to make

This is the result starting off as 1 vs 1 crab.

Yay! I never thought anyone would really make it! Twelve of my fattest cattle for you, my friend!
