The Mighty Cannonship

The Mighty Cannonship, or , is the first airship level as well as the first level of Soda Jungle in New Super Mario Bros. U. This course is unlocked via completing Larry's Torpedo Castle or Wendy's Shifting Castle and its own completion unlocks Jungle of the Giants. However, completing Blooper's Secret Lair or Piranha Plants on Ice will involve skipping The Mighty Cannonship entirely.

Layout
Bowser Jr. will come down with the Airship and snatch up the player at the beginning of the level. The first part of the level is on the deck where Cannons and Mechakoopas are ready to meet Mario. After that, the player enters a pipe that will take them into a flooded section of the ship filled with Targeting Teds and Mecha Cheeps. When the player reaches Bowser Jr., his Junior Clown Car will be in submarine mode. He will launch Targeting Teds at Mario while the pipes from the ceiling activate periodically and push Mario down. The player must guide the Targeting Teds to hit Bowser Jr.'s submarine. After three hits, Bowser Jr. will fall off stage, and the room will drain itself. However, Bowser Jr. comes back and tries to use the Mecha Hand to smash Mario, but Mario jumps out of the way and continues his voyage into Soda Jungle.
