Shrowser is the fusion of Bowser and the spirit of the Elder Princess Shroob. It is the true final boss to be encountered in the game and the eighth boss overall. Mario & Luigi: Partners in Time, though the boss battle is more like a mini-game.
After Bowser ate the purple mushroom that held the soul of Elder Princess Shroob, he got possessed by her. Mario, Luigi, and their baby forms had to fight this new threat in Princess Peach's Castle. This fight is unique because, as Shrowser says, the player cannot attack. In order to defeat Shrowser, the player must Jump over or hit back with the Hammer twenty fireballs, ten fire orbs, or a combination of both, in order to destroy purple mushrooms, which indicate Shrowser's life. After destroying all mushrooms, Elder Princess Shroob will disappear, causing Bowser to lose his power. While Bowser is possessed, he looks pretty much the same, the only difference is that he's flashing green and purple and Elder Princess Shroob is floating above him.

- Shrowser is the second final boss of a Mario & Luigi game to be a powered-up version of Bowser. The first is Bowletta from Mario & Luigi: Superstar Saga, the third is Dark Bowser from Mario & Luigi: Bowser's Inside Story, and the fourth being Dreamy Bowser from Mario & Luigi: Dream Team.
- Even though Shrowser is indeed the final boss of Mario & Luigi: Partners in Time, many believe that Elder Princess Shroob (transformed) is the final boss due to her difficulty.
- This is the only RPG boss that can be only won by counterattacking with an exception of Thunder Sass from Mario & Luigi: Dream Team. although healing Items are allowed in that battle.
