Snoozorb

Snoozorbs are large robots that appear as enemies in Mario & Luigi: Partners in Time. Their name is a portmanteau of the words 'snooze' and 'orb'. They appear in Shroob Castle, and are usually found sleeping, but wake up and attack when the Mario Bros. approach.

Battle
Snoozorbs can attack by changing into a ball and rolling into the Bros., which they must counter with the hammer. They generate steam from their head beforehand, and if the steam comes out on its right, the Snoozorb will attack Mario; if the steam comes out on its left, it will target Luigi.

Snoozorbs may also gather energy and fire a powerful laser. If the energy gathers straight towards the center, the resulting laser will be fired directly at the Bros., who must jump to dodge; the laser may also be directed in a sweeping pattern. If the energy is gathered in a spiral, it will be shot over their heads. As the Snoozorb takes more damage, it starts attacking multiple times in a single turn.
