Robo-Snot

Little Robot has an itchy nose. "AAAACHOOOO!" Out shoots some sticky, stretchy, gooey green stuff, the like of which has never been seen by robot-kind before. Soon Little Robot's snot makes him famous. He doesn't want to share it with anyone, but, just as he realises there is such a thing as too much snot, the other robots start sneezing too!
