How do you get one? I'm getting a v4 soon, I need to have one! All I know is that you need kindness/social poínt, but nothing else. Any tips? Please help!
To get Leaftchi ( which is called Violetchi on the V4 for some inexplicable reason ) you need to have a Young Memetchi or Ichigotchi teen.
Whilst they are teens you need to build a high level of Kindess/Social (Flower) points. That means playing the FLAG game much more than the Shape or Dance game, so that your Kindness points are the highest when your teen is due to evolve into an Adult
Other than that, try to keep the Happy and Hungry hearts as full as you can whilst they are a teen - especially on the second day - that usually influences the Adult they will turn into
