Mom's Rock Cave

Mom is tired of having to help the guys do their stuff every time, so Dorami takes her inside Mom's Rock Cave so she can leave her household chores behind and teach the guys a lesson on Mom's importance. Not knowing that Mom and Dorami are inside, Suneo, Gian and Shizuka mistake the gadget as the Nobis' prized possession, prompting a gang of thieves to steal the gadget when no one's in the living room.
