Back in the days of 2001, I had a particular Gold Version that my brother gave me for my birthday, since by then he was 10 and done with Pokemon. So, me being a 4 year old kid, I didn't train anything except my Feraligatr. That idea went well until the E4, where I actually had a challenge. Well, the rest of my team was Sentret, Pidgey, Geodude, Vaporeon and Magmar. Lets just say Koga toxiced me, and I didn't understand what it was being 4, and lost. This happened over and over and over again, because I didn't understand the game.
