Subway

Here's how the Subway system works: You enter the subway station (there's one in Somewhat Sump and one is Groddle Forest Junction), then to the far right of the station, there is a 'Red Button'. Push it to get one ticket, which costs 50 currants. You are then put on the train, but you have to wait until two others board until it starts moving (there have to be 3 passengers on your train). Once they're on, the train starts moving and lights flash past the window, which stop as you approach the next stop. For a few seconds, have the choice to get off there or not. If not, the train carries on going along to the next station (which at the moment is only 2 stations).
