Elder Princess Dr. Shroob
Shroobs are a species of Mushroom-like aliens. They kind of look like Toads, both being humanoid Mushrooms, apart from Shroobs being purple, having claws, and having a chubby body. They are ruled by Princess Shroob.
Shroobs also appear in Mario & Luigi Bowser's Inside Story as secret bosses. After defeating them you get the mistery window special attack.
Mario and Luigi: Paper Combine
Shroobs appear in the game Mario and Luigi: Paper Combine. They take over the Paper World and the Mushroom Kingdom. The Shroobs thawed out from the ice that was in Bowser's Castle. The Shroobs can now multiply and they can turn characters into zombies by biting them or shooting them with their ray guns. They turned Grodus into a Shroob and made a evil dark version of Luigi known as Dark Luigi like when Dimentio brainwashed Lugi and turned him into Mr. L. They use copy guns to clone enemies to attack the bros in some boss fighrs.
Shroobs are main enemies in Chapter 5, as they attempt to take over the Comet Observatory. In battle, Shroobs can bodyslam, shoot poisonous laser blasts, or call for help.
