Toad Express

The Toad Express is a pink plane owned by Peach, Mario, Toadsworth, and some Toads. They used this plane to fly to Isle Delfino in Super Mario Sunshine. The plane landed abruptly at Delfino Airstrip as a crater filled with strange Graffiti covered most of the runway and came to a screeching stop, causing Mario, Peach, and Toadsworth to jumble around inside.

In Mario & Luigi: Superstar Saga, Peach again uses this plane to get to the Beanbean Kingdom; however, when she arrives at the Beanbean International Airport, it is congested by Piranha Plants and the Mom Piranha, preventing the plane from landing. Mario and Luigi got rid of the Piranhas so the Toad Express could safely land. After the player beats the game, the plane is used by Mario, Luigi, Peach, Toadsworth and Bowser to go back to the Mushroom Kingdom (although Bowser was dropped to his castle mid-flight).

It makes a cameo in Mario Tennis: Power Tour, bringing Clay and Ace to the Mushroom Kingdom.

Appearance
Inside of the plane there appear to be four (possibly five, depending on the arrangement) Mushroom-themed seats. There are moderately large windows with elaborate curtains, many fancy details, and a stunning ceiling that is painted (or is possibly a lamp) bright blue with yellow stars and white clouds.

Trivia

 * The design of the Toad Express used in Super Mario Sunshine appears to be based on certain real-world Flying Boats and STOL Aircraft such as the Antonov An-72, while the one in Mario & Luigi: Superstar Saga is more based on 'Jumbo Jet' Aircraft such as the Boeing 747.
 * In the tourist guide to Isle Delfino under the Delfino Airstrip section, there is an airplane that looks like the Toad Express, but a blue paint job is shown.
 * In the cutscenes of Super Mario Sunshine, the Toad Express has a pink body, white underside and red on the tips of its engines. However, in gameplay, the red highlights are missing.
