While Coconuts and his friends, Oscar and Matilda, are playing on the beach, they see a spherical flying object falling into the volcano of Dragon Island. Was it a shooting star, a flying saucer, or a meteorite? When the volcano erupts with flaming rocks a little later, the friends fear an explosion that could destroy their entire island. Will the three friends manage to calm the fire-spitting mountain again? Activities and games are available for the book.
