Snowy was raised by Lilie after the egg was given to her to care for by Principle Samson Oak. The egg was brought to the school from where it was found on Mount Lanakila.
After the Pancake Race, everyone was at the Pokémon School to watch it hatch into Alola Form Vuplix. Lillie
said she had already named it Snowy and that the name came from the fact that it is white as snow and often rolls around like a ball.
The eighth match of the Top 16 round of the Alola League featured Gladion's Umbreon
verses Lillie's Vulpix (Snowy)
. The match started with Vulpix using Hail but Gladion wanted to attack quickly so that Vuplix couldn't strengthen its defense. Lillie
figured that the only one possible way they were going to win the match is by using a Z-Move and they directly hit Umbreon Subzero Slammer but it withstood the attack and fought back with an Iron Tail and knocked out Lillie's Vulpix (Snowy)
