Yes, Chansey does and can evolve in "Pokémon LeafGreen" but only after you have acquired the National Dex due to Blissey being a Pokémon that was introduced in the 2nd Generation. Chansey evolves via happiness in order to raise its happiness you have to follow the following conditions: Let it battle, feed it vitamins, keep it in your party and don't let it faint.
