"Mindy's Bedtime": Mindy has to go to bed when the Sun goes down, but she's having such a fun day with her friends. She asks Jet and the others to help her keep the Sun from going down. The older kids humor Mindy and try to help "slow down the Sun." All their efforts make Mindy so sleepy that she decides to go home and sleep. "Galileo, Galileo!": Sydney and Jet are having a hard time explaining to Mindy that the Sun doesn't move - the Earth is moving around the Sun, so the Sun seems to move. Then Sean comes over dressed as his science hero Galileo, getting ready to do a school report. Mindy asks "Galileo" to explain why the Sun seems to move, and Sean practices for his report by explaining how the planets move, in character as Galileo!
