Shroob UFOs are the Shroob's alien spaceships that they use for travel from place to place in Mario & Luigi: Partners in Time. These spaceships are small, but they can fire powerful energy bolts that can turn people into Shroob Mushrooms, as well as deal devastating damage to buildings and such.

The Shroob UFOs are first seen shortly after baby Mario defeats Baby Bowser where they bombard Peach's Castle before the clues part and unveil a massive invasion fleet. A flashback later shoes them attacking what is probably Toad Town, arriving unaware and decimating the Mushroom Kingdom capital in moments. In Hollijolli Village, Mario and Luigi have to fight an impossible battle that featured a Shroob UFO that counted down from three turns. When it reached zero,The same kind of UFO also appears in the second half of the Elder Shrooboid battle, this time counting down from four turns, but can be hit with a Spiked Ball to reset the countdown. Mario and Luigi were defeated. One later appears in a flashback after the adult Mario and Luigi are rescued where one tried to shoot baby Princess Peach, baby Mario and Luigi, Toadsworth, and baby bowser. However, since the prince had called for help from Kamek, the Koopa Cruiser arrived, destroyed the Shroob UFOs attacking the castle by ramming into them, and crushed the saucer with a caannon ball from the Koopa Cannon. Several more pursue them once the adult Mario Bros are onboard but are destroyed by the Koopa Cannon although a Shroob Missile blasts it out of the sky as they had wanted all amunition. During the battle against Swiggler, two Shroob UFOs appear whenever Swiggler drinks from its glass without any mushrooms added to it, the UFOs then fire energy blasts at the Mario Bros., although they occasionally swap positions once the boss enters Fury mode. They are not seen again until after the boss battle against Kamek outside Yoshi Village where two Shroob UFOs make Yoob giant.

Shroob UFOs also appear in battles with Blazing Shroobs within Thwomp Volcano, where they lower fireworks down to the Blazing Shroob's flames, and shoot at the Bros. with it. They can be knocked out of battle by jumping onto one of the Blazing Shroobs while they're aflame. They are impossible to hit and the only way to get rid of them is to defeat all Blazing Shroobs at which point they will fly away. In Shroob Castle, the Mario Bros. hijack bigger UFOs to destroy the smaller ones along with the Shroob Mother Ship.

Shroob UFOs are powered by the Toad species' lifeforce 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 afterwards used as fuel for the Shroob UFOs. In Hollijolli Village, they are summoned using a device that strongly resembles a Nintendo DS.

With the end\imprisonment of the Shroobs within Bowser's Castle, it remains unclear what happened to the Shroob UFOs but the baby tears mixture probably either evaporated them or they were either placed into museums or destroyed to prevent them form ever being used again.
