Rooney has a new invention: the Robo-Moe. It looks and acts just like Moe. This gives Moe an opportunity to attend his drumming club meeting, while Robo-Moe attempts to sub for all of the day's activities. Robo-Moe has a catch though; Rooney made him not as loud or messy. At first they think it's a good thing, but learn that nothing should replace Moe.
