Velvet and Elmo imagine up some tools to base today's musical around, but Elmo doesn't think they're suitable subjects. He decides to use them all and become a Repair Monster. Now in a park, Elmo finds he has to fix some things that are split in half somehow. The disasters are caused by The Great Halfini, who's trying to split his hot dog in half, but can't. Soon, everything in the park is split in half. Repair Monster Elmo discovers his wand is as well and fixes it. The two restore the park to its whole glory.
