Synopsis
Sesame Street is having the greatest number lover convention of the year, Numeric Con, where everyone gets together to celebrate their favorite number. Leela is dressed as her favorite hero, Princess THREE-ah, and Elmo is dressed as The Dark NINE. There is so much to do at the convention, so Leela helps Elmo create a plan to focus on the things he wants to do most.
As they check things off of Elmo's plan, Elmo also helps the number character Doctor TWO figure out how many aliens he's traveled with by counting by twos, and he shows the FIVEarine how to sign his autographs with the number five using just one crayon. When Elmo is ready to do the last thing on his list, count to 10 with his favorite number hero, The Green LanTEN, he finds out that The Green LanTEN has already left the convention.
Elmo gets upset because it was part of the plan, but Leela explains that Elmo helped solve everyone else's problems, so maybe he can solve this one too. She suggests that he could be flexible and just change his plan. Elmo agrees and tries to come up with a new plan so that he can finish his plan.
