Gabi is reading Elmo a book called Dinosaurs, Dinosaurs, Dinosaurs because Elmo loves dinosaurs! When Gabi has to leave to go to class, Elmo imagines himself with a pet dinosaur and sings a song about all the fun things they would do together.
Elmo decides to ask Gina where he might find a pet dinosaur. Gina tells Elmo that dinosaurs are extinct and explains that dinosaurs lived a very long time ago, but there aren’t anymore left anywhere. Snuffy finds Elmo upset and asks him what is wrong. When Elmo explains how he really wanted a pet dinosaur, Snuffy has an idea. He comes back dressed in a dinosaur costume pretending to be a Shaggy Snufflesaurus and looking to be someone’s pet.
Elmo gets very excited. They sing a song about all the fun things they will do together and leave to go on a walk. This dinosaur needs lots of exercise, as well as cabbage and spaghetti
