The same students we met in Field Trip to the Moon and Field Trip to the Ocean Deep travel to a volcano island on a yellow school bus helicopter. When they get there, one student picks flowers as they hike to the top and then accidentally slips down a crater and can't get out.The student isn't too worried--especially when he meets a lava monster and its children who are fascinated by the flowers. But when they touch them, they burn beyond recognition so the student teaches them how to make a vase using lava from a lava pit, fills it with water from a canteen, and they all sit back to enjoy the flower arrangement until help arrives and rescues the student.
