This story takes place after the episode "Daring Don't"
Daring Do was tricked by a client who pushed her into a Fountain of Youth and was regressed into a foal. She then finds Ahuizotl (who was also regressed into a kitten). Now the two have to trek through the jungles of the Tenochtitlan Basin and find a way to turn back into adults. Meanwhile, the "client" uses the waters from the fountain of youth to take over Ponyville as The Apple Family regress into foals; their rivals Flim and Flam take over the Apples' farm, and Mayor Mare is regressed into a foal as well. Daring Do and Ahuizotl now race against time to turn back into adults and save Ponyvile from the mysterious mare's takeover.
