Dinosaurs - Reptiles and Invertabrates Play School : Season 26 Episode 38

aka ep34.3 Trisha and Philip do a huge jigsaw puzzle of a Plesiosaur. The puzzle pieces (cardboard) have magnetic strips to stick them to a whiteboard. Some jellyfish, a starfish and a sea urchin visit the studio. A hoop with a muslin centre and dangling streamers becomes a dress-up jellyfish for the presenters, while they sing 'A-Blob, a-blob' to the tune of the Mexican Hat Dance ('Jarabe Tapatío'). The story of 'The Triceratops Twins' is told in the sand tray with plastic dinosaur figurines. Through the windows crocodiles hatch.
