Shrooba Divers are green Shroobs with white spots from Mario & Luigi: Partners in Time that wear scuba masks and oxygen tanks. These Shroobs have the unique ability to "swim" in sand; their name is a pun on "Shroob" and "scuba diver". Shrooba Divers are stationed in the Gritzy Desert.
In battle, Shrooba Divers employed a variety of attacks and techniques to defeat their opponents. First, a Shrooba Diver digs in the sand and pull out various objects to harm the Mario brothers with. A Shrooba Diver may pull out a Spiny Egg and toss it at the Mario brother. This attack can be jumped over. The hand it throws it with determines which brother will get hit. Occasionally, the green Shroob would pull out a Blurp. These Blurp-like creatures from the previous game bounce, meaning the fish would flop right over the Mario brother's head, which can fake out the Mario brother. Secondly, a Shrooba Diver could tunnel under the sand (indicating which brother it is going to attack beforehand), leap out, then dive into a Mario brother. This attack could be countered with a Hammer. Lastly, a Shroob Diver would try to swim into a brother. This can countered with a jump attack.
