Shroobs are one of the main enemies in the game Mario & Luigi: Partners in Time and an optional enemy in Mario & Luigi: Bowser's Inside Story. They plan to destroy everything in the past Mushroom World and make it their new home. So Mario, Luigi, and a whole cast of other Mario characters plan to stop them. Their leader is Princess Shroob.
They look much like a Toad, except with bright red eyes, purple skin, and claws as hands. They also have two pointed teeth visible from their mouths. White spots can be seen on the top of their heads.
- Princess Shroob - Leader of the Shroobs. Under her command, the Shroobs attacked and invaded the Mushroom Kingdom. She is one of the final bosses, right before the Elder Princess Shroob.
- Yoob - This is a Yoshi that turned into a giant purple Yoshi Shroob that attacks anything. It seems to eat any living thing as well, converting the Yoshis into eggs for energy.
- Swiggler - One of the bosses in the game. He resembles a Wiggler, though is much stronger, and colored purple. It provides fuel for the Shroob UFOs.
There are multiple different Shroob enemies in the video game. Seven of them are "remakes" of common enemies that often appear in the Mario series. These enemies can be seen to the left. Other than the Shroob enemies listed, there are many other Shroob enemies as well that will appear in the game, such as Dr. Shroob, Commander Shroob, and many others.
Dr. Shroobs are some of the enemies that you will find in the Shroob Vim Factory. They are orange with white spots, and have crazy looking eyes. They can create Shroob Shrooms, and can prove to be a challenge for players.
Shroobsworth is the Shroob equivalent of Toadsworth, although there's more than one. They appear in Princess Peach's Castle of the past. They each carry one Intern Shroob on their backs and have the ability to throw up their Intern Shroob really high, and use a Matrix-esque attack on Mario and co.
Intern Shroobs are basically young Shroobs which ride on the backs of different Shroobsworths. They have Shroob blasters, and use these to hurt Mario and company.
Support Shroobs carry Shroob-ombs, the Shroob version of a Bob-omb. They are found during the Shroob Commander battle on top of Star Hill. If Mario and company defeat two of them, the Shroob-omb will roll in the direction away from the last Support Shroob.
- Shrooblet: The weakest of the Shroobs that has resemblance to Goombas.
- Shroid: A robotic Shroob that uses a cannon in its arm and red and green flags to attack.
- Shrooba Divers: Green Shroobs that swim through sand in Gritzy Desert.
- Guardian Shroob: White Shroobs that are faster than regular Shroobs and can call in more Guardian Shroobs.
- Blazing Shroob: Red Shroobs who are usually on fire. they toss fireballs, call in a Shroob ship to toss firecrackers, and shoot lasers.
