I was playing Crystal a long time ago, I had gone to the day care man. At the time, I had Quilava, Pidgeotto, Rattata, and a Metapod. Of course, I was about seven at the time, and still didn't really know what the characters were saying.
All I knew at the time was 'Yes' usually meant I got something *child-like innocence, never fails :P * good. I said yes and accepted an Odd Egg. Confused as to why I couldn't battle with it, I asked my older brother, who COULD actually understand, and said I should wait.
Sure enough, the Odd Egg hatched, and I was gifted a shiny Pichu with Dizzy punch. Note that from Gen I, Raichu was my favorite Pokemon, and when I was told that Pichu was the Pokemon before Pikachu, I was ecstatic.
From there, I have met THE RED GYRADOS! Fire-Red/Leaf-Green I saw a Shiny Tangela, and a shiny Chansey. For Sapphire, I encountered shiny Kyogre *on the first try, can you believe it?!*
