There are so many Simple Bots that sweep and scrub, that I felt it only appropriate to make one that picks up after them. Scoop does just that. It pushes itself around and systematically scoops up whatever lies in its path. Well... maybe "systematically" is too strong of a word to use in describing it, but it definitely gets an A+ for effort. If there is one thing that Scoop Bot wants to do more than anything else in this world, that is scoop. There is not a man, woman, ice cream server, or investigative journalist alive, quite as dedicated to scooping.
