Shrowser is Bowser with the power of the Shroobs infused, in the video game Mario & Luigi: Partners in Time. He can still breathe fire in this form but this time he does not give the Mario Bros. and the little bros. any chance to attack. In the beginning of the Shrowser battle Shrowser spews a purplish gas out of his mouth which turns into the ghost of the Elder Princess Shroob. The only way to defeat Shrowser since he does not let you attack is to both dodge his small fire attacks and then those will keep flying until they hit the Elder Princess Shroob's ghost and then to use hammers to counter the bigger flames he spews. The ghost princess has a health meter this time around so you don't have to keep guessing on whether or not she's close to being truly dead.
