Feed it items like carbos, protein, etc. Feed it the poffins it likes, take it to the resort area for a spa treatment once a day, keep it in the front of your taem, raise it, and give it a soothe bell.
You need to make Eevee love you, and then you evolve it at night.
you have to give it loads of love
you need to get evee and give it love in the morning to get Espeon and at night to get Umbreon
When your eevee has max love for you, train it up at night.
depends on happiness espeon during the day umbreon at night
To make Eevee evolve into an Umbreon, you have to level it up with high happiness at night.
You can't 'see' an umbreon in Platinum. You have to level an eevee at night, or make it friendly. That counts as catching it and seeing it.
Make Eevee as happy as you can. For Umbreon, level it up at night. For Espeon, level Eevee up in the day.
first go to your house and check if it is pm. if it is then train it and it will evolve into an umbreon but if it say am it will be a espion
Sorry to say but, eevee doesnt evovle into umbreon by level. The only way to make it evolve at night with high happiness
On Route 212, a trainer has it. That is, if you just want to see it to complete the dex. There is no where to catch it on platinum, though. You'll have to make an eevee happy at night to make it evolve into an 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
