The Go Go Dino Explorers were playing volleyball on the beach. But Tom hit the volleyball so hard that it flew into the Tylosaurus' nostril. The Tylosaurus was in great pain but the Dino Explorers didn't know that when they returned to the base. The Tylosaurus was struggling painfully in the sea and the animals under the sea got frightened. Then the Go Go Dino Explorers set off to help.
