Shroob

The Shroobs are a race of aliens that attacked The Mushroom Kingdom of the past when Mario and Luigi were babies. These events take place in the game Mario & Luigi: Partners in Time. They are a purple, mushroom-like species ruled by Princess Shroob and her older sister. Most Shroobs carry ray guns with them. Unlike Toads who are seemingly more human than mushroom, Shroobs seem to have retained most of there fungus ancestry.

They possess a massive fleet of flying saucers, which are powered by the vim of Toads. The saucers are capable of shooting lasers and energy beams.

The Shroob military is very complex in their processes. Unlike the Koopa Troop, the Shroobs have everything laid out in advance so that they could both protect vital operations and invade enemy regions at the same time. A few complex military operations include:
 * The invasion and destruction of Toad Town, including the capture of many Toads. These Toads were taken to Toadwood Forest, where their vim was drained by the forestsâ€™ trees. The vim is then collected at the Vim Factory, where Dr. Shroobs gave the vim to Swiggler, a bio-engineered Shroob Wiggler. While guarding a Cobalt Star Shard, Swiggler also drinks the vim and powers the Shroob UFOs.
 * The creation of Yoob and the attack on Yoshiâ€™s Island. Yoob would eat any Yoshi it could find. These Yoshis would then be converted into more monstrous Yoobs and be used to attack the Mushroom Kingdom.
