Episode Title:
Time Waits for No Frog/Einstein's Adventure.
Episode Description:
Time Waits for No Frog: Doc and Marty go to South America in 1532 to find a cure for Marty's athletes' foot. The cure comes in the form of an extinct frog—the Bufo marinus—which emits an acid from its skin. Doc and Marty meet up with the vile conquistador Biffando and his goons. Biffando releases them and follows them at a distance, to the Lost City of Gold. Marty and Doc end up being captured by Incas and are put in a large pit with hundreds of Bufo marinus frogs. With that many frogs, Doc says that he and Marty will "melt like the Wicked Witch of the West" from The Wizard of Oz. Using a tuning fork, Doc makes the frogs go crazy and it looks like Marty can "control" the frogs. The Incans release Doc and Marty and stop Biffando from stealing any gold. Doc and Marty take a couple of frogs home to reestablish the population in the 20th century.
Einstein's Adventure: While Doc is in the hardware store, Einstein is asleep in the back of the DeLorean when it is stolen by a couple of bank robbers. The robbers activate the DeLorean's time circuits and head to Sydney, Australia, 1790. Einstein is bounced out of the car on impact and the robbers end up "breaking in" to an Australian prison. Einstein ends up saving the crooks and when they get back to the future, the crooks return the money and turn themselves in.
