The Japanese Tamagotchi website shows two version of the Eevee Tamagotchi. One is roughly translated as “I Love You, Eevee” while the other is simply “Colourful Friends.”
Whichever your preferred colour, you’ll be able to raise your Eevee as you would a Tamagotchi. This involves feeding them, washing after them, and it will eventually evolve into one of the eight possible Eeveelutions.
The Eevee Tamagotchi is slated to be released in Japan on 26 January 2019, and for JPY2300 (~RM85). So far, there’s nothing about a release outside of Japan, but if there is we’ll probably hear about it.
