Bat Pat season 1 episode 20

Episode title: Ocean's Roar

Summer has officially started and the people of Fogville are hitting the beach, including the Silver family and Bat Pat. But their plans are derailed when a series of huge "potholes" in the street have jammed the traffic. The kids and Bat Pat eventually realise that the potholes are really footprints caused by a T-Rex that had been frozen in a block of ice.
