That's what children will see here. Even though 19th century Sesame Street started out unfriendly, one new arrival changed that. Just that one very act of kindness had a domino effect, and that made Sesame Street friendly in no time flat. This is a lesson that parents will want to reinforce with their children. The only reason why I put the green light at 4 rather than 2 or 3 is because the jumps between flashback and present day could be confusing for very young children, especially since their ancestors share the same names as their present-day counterparts.
