Maghi was a happy dinosaur who lived during the Jurassic period. He had many friends, including Cory. One day, Maghi and Cory were walking home when they met a predatory dinosaur named Alosaur who wanted to play with them. The three dinosaurs then went to Maghi's house to play all day, dancing and telling stories. When evening came, Cory and Alosaur said goodbye to Maghi, promising to come back another time.
