List of Minor Characters in Peanuts - 3 and 4

3 and 4 were the twin sisters of 5 and were named by their parents who were giving into all the numbers that are required in everyone's life. All three siblings appear in A Charlie Brown Christmas where they have non-speaking roles, but demonstrate distinctive 1960s dance moves during the dancing scene. The pair appeared occasionally until the mid-1960s; at least one strip has one of the girls by herself, chatting with Charlie Brown and Snoopy.
