The chalk boy turns on the Chalkomputer and starts the game called "Prehistoric Rescue Mission" where they have to save little dinosaurs from falling meteors.
Tessa and Stuffie have a great time, but it's the chalk boy who really immerse himself in the game. When he wins, he always does a little victory dance.
Time flies in good company, so Tessa and Stuffie are surprised to realize that they have to set off. The chalk boy becomes sad, his former cheerfulness is completely gone. He turns the computer off in disappointment.
