Shroob UFO
From the Super Mario Wiki
This article is about the Vehicles used by the Shroobs. For information about the flying object in Fourside, see UFO (Fourside).
Shroob UFOs, also known as ShroobFOs are the Shroobs' alien spaceships that they use for travel from place to place in Mario & Luigi: Partners in Time. These spaceships are small, but they can shoot powerful energy bolts that can turn people into Shroob Mushrooms, as well as deal devastating damage to buildings and such.
In the Yoshi Village, the Shroobs used their Shroob UFOs to shoot and mutate Yoob, a Shroobified Yoshi.
Shroob UFOS are powered by Toad energy, known as vim. The vim is sucked out of the Toads by the trees of Toadwood Forest mixed with chemicals at the Vim Factory, and afterward used as fuel for the Shroob UFOs. In the final part of the battle against the Elder Shrooboid, there is a special UFO with a timer, and if the timer hits zero, the UFO will instantly defeat the four Mario Bros. The same kind of UFO appears in the impossible battle with the three shroobs who kidnapped the mayor of Hollijolli village when the adults fight them. They were called by something that strongly resembles a Nintendo DS.
