S50, E21: Elmo, Rudy, and Abby play superheroes with their toys while Big Bird and Julia paint nearby. Rudy wants to play with another toy and spots Fluffster, Julia's toy, on a table. But as soon as he takes Fluffster, Julia gets upset. Alan explains that Fluffster is Julia's special toy that helps her calm down so it's not a toy she likes to share. Rudy understands how Julia feels and apologizes for taking Fluffster. And even without sharing their special toys, they all find a way to play together.
