The Jetsons (1962)

S2E3 Solar Snoops

Spacely Sprockets receives a mysterious delivery: a robotic guard dog named "Sentro." Eager to protect his prized "Chocolate Microchip Cookie," Spacely enlists Sentro’s help. However, the "Galactic Sneak," a covert operative for Cogswell Cogs, has cleverly hidden inside Sentro to execute his plan. After the duo successfully absconds with the coveted Microchip Cookie, it falls to George Jetson to take action. Spotting a job listing for an executive assistant at Cogswell Cogs, he transforms into "Georgina Jetstream" in a daring effort to reclaim Spacely's cookie.
