Those Original Three

 is the second part of episode 4 of Eevee-lutions.

Summary
The Eevee-lutions stumble across Professor Oak's lab and meet a Pokemon named Bulbasaur. Bulbasaur's desire is to go on an adventure beyond Kanto, but she is never chosen as a starter Pokemon, as new trainers tend to favor Charmander and Squirtle more. The Eevee-lutions proceed to try to find Bulbasaur a trainer, but they just can't get their points across to the humans. In the end, however, a human girl named Moon falls absolutely in love with Bulbasaur and picks her as her starter Pokemon.
