You have to wait a while after you get to pick who evee will evolve into (umbreon) You have to wait a while after you get to pick who evee will evolve into (umbreon)

Eevee doesn't evolve into Umbreon with a stone. Eevee evolves into Umbreon when it is levelled up with high happiness during the night.
To make Eevee evolve into an Umbreon, you have to level it up with high happiness at night.
Eevee doesn't have a set level to evolve into Umbreon. All you have to do to evolve it is max out its happiness at night. ~KKMG1
No; Umbreon didn't exist that early in the series.
Train your Eevee at night and with happiness. It will eventually evolve into Umbreon.
You evolve espeon at day by making it like you, you get umbreon by making it friendly at night and also by leveling it up
You will need to have your Eevee to full Happiness, then level it up at least once during the night to evolve it into Umbreon.
usually by happiness at night but what i do is give it a moon stone to hold then level it up once. trust me i tried it multiple times and it works
