Built by Jelle’s Marble Runs, Marblopolis is a marble run amusement park featuring 30 different attractions, all connected via almost 1/4 mile of track. The park can accommodate up to 400 fun-loving marbles at a time, and, I think I speak for everyone here when I ask, what happens if a 401st visitor shows up? Do all the rides break? If that marble were me, it would probably ride something spinny then puke funnel cake on another marble, who would then puke on another marble, and on and on. Like a domino maze, but a puking marble run.
