This worm is an experiment of the Stickcity National Research Central. The worm, displayed in a brick wall through the shiny glass from the tripod, follow your mouse movements. It takes its time, and its laziness also causes it to split up sometimes! But do not worry, this was an error. They have mutated parts now!
The director, Stickman, had came up with this idea. He manipulated the test subject (which was a robot) to follow mysterious patterns.
