You RP as one of the Baby Eeveelutions in a Pokémon Daycare! Choose your Eeveelution of choice (including Eevee). The ones you don't pick will be the other characters.

Your owner drops you off before he goes to work, you don't mind going to the daycare, they help you learn how to play nice with other Pokémon and how to think like a big kid. You have a few other friends there. Your caretaker takes you and the group of Pokémon into the playpen and they start your day.
