World 3-Cannon (New Super Mario Bros. 2)
From the Super Mario Wiki, the Mario encyclopedia
The player begins on jungle grounds in front of the Warp Cannon. Entering the Warp Cannon will initiate a countdown, then the player is blasted off. The player will not be able to stop running during the level. First, Mario/Luigi will come across a Scuttlebug, followed by a Wiggler. Then a Red Ring can be found in between a Scuttlebug and a Wiggler. If all the Red Coins are collected, the player will receive a Gold Flower in their storage. The level continues with more Scuttlebugs and Wigglers. After a few of them are encountered, the level ends.
