For my first generation, Gen 2, I had no clue that trade evolutions existed. Some of the coolest Pokemon I thought were Scizor, Gengar and Steelix. So I caught Scyther, Haunter and an Onix, using rare candies, items, leveling up them as high as somewhere in the Lv. 80s. You know who did finally evolved at the Lv. 80s. My Eevee into an Umbreon lol. I had no clue how Eevee evolved into an Umbreon at the time and tried using a moonstone. There was a moonstone and a sunstone and there was Umbreon and Espeon, so my logic dictated that they evolved through this... only they didn't. While I was wasting rare candies and medicines on the trade evolutions, I was wondering how the heck does Eevee evolve into Umbreon? This got even more confusing by the time I got Ruby version and Leafgreen version which does not have the Day & Night cycle lol... which heavily conflicts with XD Gale of Darkness where you can evolve Eevee into Umbreon through the Moon Shard.
