Doctor Monkey / Curious George, the Architect

S1, E12: Doctor Monkey: When George accompanies The Man with the Yellow Hat to Dr. Baker’s office for his annual check-up, he discovers that a stethoscope is a pretty handy thing to have around when you’re trying to solve a puzzle involving a mysterious sound. Curious George the Architect: Mr. Glass is building a new skyscraper in the neighborhood, and George and Gnocchi think that his construction site is more fun than a playground. George learns how bulldozers, cement mixers and jackhammers work, and why it’s not a good idea to let a monkey operate them.
