The Garakuta Monster is a sub-boss fought near the end of Mario & Luigi RPG 3. It is a robotic creature resembling a trash can. It is helped by several smaller monsters known as Garakuta Kobun.

The Garakuta Monster is encountered while infiltrating Peach's Castle near the end of the game. Upon entering a certain area of the garden, Yellow Star will comment that there is a lot of garbage laying about. After Mario and Luigi progress to the end of this area, Metaboss appears, holding some sort of remote control. When it is activated, the Garakuta Monster springs to life from the piles of garbage laying around the area. After Metaboss's attempts to control it fail, he smashes the remote and allows it to fight the Mario Bros. on its own.

In battle, the Garakuta Monster has a variety of attacks.
 * One attack consists of throwing a bucket over either Mario's or Luigi's head. The brother will then stumble around blindly while the Garakuta Monster throws Thwomps at him. Players must cause the brother to jump with good timing to avoid the attack.
 * Another attack involves throwing two balls of metal scrap at a bro, then attempting to ram him. The Mario Brother in question must jump onto the metal balls, then jump over the Garakuta Monster as it attempts the ramming portion of the attack.
 * A third attack consists of emptying the garbage from one of the Garakuta Kobun that follow it. Often, this garbage will consist of random enemies that go after the Mario Bros, each of which must be dodged in a different way. Once several enemies have attacked, the Garakuta Kobun will be discarded.
 * The Garakuta Monster may also choose to hinder the Mario Bros. by incapacitating Luigi. It does this by putting Luigi into a Garakuta Kobun. Since this attack cannot be dodged, Mario will be forced to defeat the Garakuta Kobun to rescue Luigi.

After the battle, the Garakuta Monster begins to malfunction again, rampaging around and freeing Bowser from captivity in the process. It then destroys itself by running into a locked gate, opening said gate in the process. This allows the Marios to access a pipe connecting Peach's Castle to Pipe Plaza
