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. While curled up, they resemble Big Steelies.

Battle
Snoozorbs start the battle asleep, and thus do not attack until waken by the Bros. They only have two attacks, and indicate both of them with steam pouring from their heads. If the steam comes out of its right, the Snoozorb will attack Mario; if the steam comes out of its left, it will target Luigi.

Snoozorbs can attack by changing into a ball and rolling into the Bros., which they must counter repeatedly with the hammer. They will not attempt this attack if the player does not have the baby brothers with them, as only the babies have the hammers to counter it. Unlike most enemy attacks, successfully countering this does no damage to the Snoozorb.

Snoozorbs may also gather energy and fire a powerful laser. If the energy gathers straight towards the center, the laser will be fired directly at the Bros., who must jump to dodge; the laser may also be directed in a sweeping line to hit both Bros.. If the energy is gathered in a spiral, it will be shot over their heads, which will only hit the Bro. if they jump into it. As the Snoozorb takes more damage, it may fire multiple lasers in a single turn.
