Space Or Click New OC! Boiler Bills are a fleet of steam engines built by Bowser's army. They can be used both as private trains and weapons, as their boilers are actually secret Bullet Bills. When needed, they leave their "main bodies" and fly off into the required target, while the Tender takes the care of the train. A Boiler Bill would appear at the end of an auto-scrolling train level. Once you get on top of him, he takes off, and you can control him by standing on each end. If you don't crash, you compelete the stage as intended, but if you will, the crash will lead you to a secret exit. Credits: HiT for the music i suppose
