Pokemon Sun & Moon

Synopsis

Lillie's egg, which she had named "Snowy" in the previous episode, hatches into an Alolan Vulpix and the principal's egg into a normal Vulpix. The fire-type Vulpix starts playing with Pikachu, Togedemaru, Popplio, and the others, while Snowy (an ice-type) ignores the others. Finally, it decides to accept Lillie as its trainer and enters Lillie's Pokéball on its own. Lillie decides to spend some time alone with her newfound partner and takes a walk with Snowy, while being followed secretly by Mallow and Ash. Team Rocket also starts following them and soon corners Lillie and Snowy. Although Lillie tries to put up a fight with Snowy using Powder Snow, Team Rocket dominates her in battle. She and Snowy are saved by Ash and Mallow. Lillie finally is able to touch a Pokémon, although she is only able to touch Snowy for now.
