Ages 3 to 5 years. During another magical sunset in New York, Maxi the Taxi Dog and Jim are playing their "Guess what street we are on?" game. They are soon interrupted by their first fare, Tupa. Tupa is in a hurry to get to his night custodian job at the Museum, but they quickly discover that Tupa has a problem. Tupa must clean dark galleries in the museum at night-time but is afraid of the dark. Even being in the room long enough to turn on the light is making it very hard for him to do his job. Maxi jumps to the rescue and decides to sneak into the museum with Tupa to help Tupa overcome his fear. Maxi makes Tupa feel so confident by helping him throughout his shift, that when Tupa must go back into a room alone he has all the skills he needs to overcome his fears.
