Morton's Airship is the second one and he is the second boss in Super Mario Bros. 3. The Airship is armed with numerous cannons and Bullet Bill Blasters at the beginning. Once halfway through, Mario or Luigi makes his way to the cargo deck where Bullet Bill blasters are waiting for him. Straying away from that he encounters some of the Rocky Wrench crew and makes his way to the Koopa Cabin where Morton Koopa Jr. awaits.
Morton is slower than his brother Larry but faster on the draw. Mario has to repeat the same process stomp him on the head three times while avoiding the wand blasts and Morton himself and thus reclaim the wand.
