Fireman Sam (1987)

S07E16 Dinosaur Hunt

While exploring the beach, Norman Price and Trevor Evans stumble upon an ammonite, which sparks Norman's imagination to craft a realistic dinosaur experience for James and Sarah. Excited by the "dinosaur growls," James rushes into a cave, only to find himself and Norman trapped by the quickly rising tide. At the same time, Sarah finds herself stuck on a rock. Fortunately, Sam and Penny arrive just in time to save the day.
