Cosmic Car Key

The Cosmic Car Key is a Mount-summoning item. When used, it summons a rideable UFO that allows the player to fly and hover indefinitely. It is dropped by the Martian Saucer boss during the Martian Madness event.

Tips

 * When using this mount, it may be useful to replace accessories such as any Wings or Boots.
 * Using wings with a fast ascent speed such as Fishron Wings, it is possible to fly upwards with the wings, deploy the mount and maintain the speed of the wings beyond the duration of the wings.
 * Using the Rod of Discord can be a great way to travel while using this mount, as you can teleport through tight areas rather than dismounting the UFO.
 * It's possible to give this mount to a fellow player while mounted and still keep using the UFO.

Trivia

 * The buff tooltip is a reference to the film Independence Day, in which a Macintosh computer is used against an alien spaceship.
