Koopa Cruiser

The Koopa Cruiser is Bowser's airship. It was used in Mario and Luigi: Superstar Saga to transport Mario, Luigi, and Bowser to the BeanBean Kingdom. After the battle against Fawful, the Koopa Cruiser crashed down to Stardust Fields. The Cruiser was later used by Bowletta to capture Princess Peach, who turned out to be Luigi in disguise.

The Koopa Cruiser was used again in Mario and Luigi: Partners in Time to evacuate Baby Bowser, Baby Mario, Baby Luigi, Baby Peach and the young Toadsworth from Peach's Castle after it's attacked by Shroob UFOs. The Shroob UFOs attack the Cruiser forcing it to drop altitude over Hollijolli Village. Baby Bowser is coaxed into into rescuing Mario and Luigi from the Shroobs and the Bros. are brought aboard. As the Cruiser flys over Peach's Castle, which had been captured by the Shroobs and was then called Shroob Castle, Princess Shroob launched a missle that shot down the Cruiser sending it crashing into Bowser's Castle.
