Mindy Turns Five

At the end of Part One, Mindy says, "This is one small step for Mindy, and one giant leap for Stuffy Bear!" and she steps on the camera. At the beginning of Part Two, Mindy says it again and her stepping on the camera is accompanied with puff effects and the other kids cheering. Also, PBS doesn't have commercials, so live-action segments with Astronomer Amy Mainzer are used to fill the timeslot on this show.
