Mysterious pipe

The mysterious pipe is a special Warp Pipe found in The Super Mario Bros. Movie that transports Mario and Luigi to the Mushroom Kingdom and the Dark Lands respectively. The pipe is located in the drains of Brooklyn in the utility tunnel, where the brothers end up in after breaking through a brick wall in the drain. Unlike regular Warp Pipes, the mysterious pipe sucks up things into it and transports them through the Warp Zone "into a magical new world." While in the Warp Zone, the brothers get transported through a transparent tunnel, but get separated and sent into two different kingdoms. Also unlike regular Warp Pipes, the mysterious pipe flashes when things come in or out of it.

At the end of the movie during the Bomber Bill pursuing scene, Mario tricks it into flying inside the mysterious pipe. The Bomber Bill shrinks and blows up while inside the Warp Zone. This causes a shockwave at first, which damages Mario, but then starts to suck everything back to Brooklyn, including the characters and Bowser's ship.
