Walking alligators

Walking Dinosaur Heads are enemies in Twang. They resemble alligators, with only being a green body, with feet, a nose, eyes, and a mouth. They hurt Black Ball if he touches them, and he will lose a heart. They can walk on any kind of line, including Invisible lines. Walking Dinosaur Heads also have no arms, and will only walk in a set path back and forth. They can also walk through lines, and will turn around when they come to an edge.
