Warp Cannon

A Warp Cannon is a cannon in New Super Mario Bros. and New Super Mario Bros. Wii that allows the player to go to different world. It is like the Warp Zone, but uses a cannon instead of a pipe. They are gotten by finding an alternate, hidden exit with a red flag. It is entered like a Warp Pipe. It leads the player to a pre-selected world that is usually some worlds away from the world where the Warp Cannon is found.
