Guardian Shroob

A Guardian Shroob is a white Shroob with blue spots. They are stronger and have faster attacks than normal Shroobs. Guardian Shroobs are found in the Shroob Mother Ship. Guardian Shroobs aid other Guardian Shroobs in battle.

In battle, a Guardian Shroob can call a fellow Guardian Shroob to aid in its attack. The two Shroobs approach the Mario brothers and fire two quick energy blasts from their ray guns, one for each Mario brother. To dodge this attack, the Mario brothers can simply jump over the energy blasts. They can also attack by themselves, just like an ordinary Shroob.
