Larry Koopa's Airship is the first Airship and first boss battle in Super Mario Bros. 3. The Airship is equipped with cannons and Bullet Bill shooters at the beginning. Halfway through, the cannons are set on the ground and ceiling to shoot from different directions and angles at Mario. Before reaching Larry's cabin Rocky Wrenches will ambush Mario and throw wrenches at him. Then there is one more Bullet Bill blaster right at the cabin. Mario then goes down the pipe.
Battle with Larry
Larry Koopa, Bowser's youngest is waiting in the cabin. He fights by shooting blasts from the wand and jumps in the air. Mario must run under him when he jumps and stomp him on the head three times to defeat him and take back the wand.
