What ride in Disneyland, California is based off a movie starring Jumbo Jr.?
Golden Zephyr:  Unlike its cousins Dumbo and the Astro Orbiter next door in Disneyland, the Golden Zephyr rockets are controlled by centripetal motion over Paradise Bay and can not be automatically controlled to go up and down. Dumbo:  The main character is Jumbo Jr., a semi-anthropomorphic elephant who is cruelly nicknamed "Dumbo".
