World 1-Cannon is the first Cannon in New Super Mario Bros. 2, and it leads to World Mushroom. This Cannon has green Koopa Paratroopas, and a Red Ring. In order to unlock this Cannon, you must find World 1-Fortress's secret exit.
This level is an autoscroller where Mario automatically runs, even if you don't do anything. Your main focus on this level is to control your jumps to get across from platform to platform. This level is mainly composed of Koopa Paratroopas and is quite easy while you hold the jump button to get additional height. If you complete this level, you will unlock World Mushroom.
