This idea was originally thought of by Samkio, in his "Big Scary Thing" plugins. It would create very basic worms out of blocks (sponge and glowstone), and each block would teleport for the worm to move. I can't believe someone hasn't further worked on this concept, as the potential is pretty amazing. Can someone take this and improve it? Anyone interested?
