Mister Rogers tries on different masks. Joe Negri is taking a census to learn if anyone has seen the red monster that frightened Sara Saturday. Betty Aberlin stops by dressed as a red monster and King Friday has set up a radar to alert them in the monster is nearby. Handyman Negri reports that, with the exception of Sara Saturday, no one in the real neighborhood or in the Neighborhood of Make-Believe has ever seen any monsters. Mister Rogers receives an invitation to watch the Neighborhood Ballet Company.
