Deerlings in the wild are always in their spring form, and the deerling I caught don't change either!
I tried 3 months in a row to see If it would change,but they don't!
Please, help Is appreciated.
There is no way to find the other forms of Deerling in X and Y or ORAS. The seasons mechanic from Gen V was removed in those games, so the Deerling will only appear in the wild as their Spring form. The only way to get a Winter, Autumn, or Summer Deerling (or Sawsbuck) in the newer games is to transfer them over from Black and White or Black 2 and White 2.
