How the Big Mouse Ears Came to Be
Disney artist Roy Williams first suggested to producers that the Mouseketeers wear hats with large mouse ears, and it was an instant hit. The girls wore a large pair of plastic Minnie ears, and the boys wore Mickey’s ears. There was an A team (Red Team) and a B team (Blue Team).

The Red Team was the cast members who took part in most of the episodes, while the Blue Team members were mostly on standby just in case they needed extra hands for the show. Nine children made up the original Mouseketeer Red-Teamers, including Sharon Baird, Annette Funicello, and Tommy Cole.
