Dinosaur in the Laundromat
Zoe, Rosita, and Rudy are intrigued by a mysterious rumbling sound on Sesame Street. They enlist the help of Bill Nye the Science Guy, who teaches them about different types of scientists and their methods. After encountering a skunk and dismissing the subway as the source of the noise, the monsters use their newfound scientific skills to trace the sound to the Laundromat. Inside, they discover Chris's laundry, including a toy dinosaur he had been searching for. Rudy, who initially guessed that the sound was made by a dinosaur, is proven right. Encouraging viewers to be scientists too, Rosita and Zoe clarify that there aren't any real dinosaurs on Sesame Street, only for Herb to make an appearance.
