I traded over Shiny Totodile to HeartGold recently, and restarted SoulSilver and picked Chikorita as my starter! More to follow.
I nicknamed my Chikorita "Autumn" and whirled through to Mr. Pokemon's house, grabbing the Apricorn Box (seriously that man is stupid, I'll go past your house if I want to) and was soon involved in a mixup of identity. I told them that Silver had stolen Cyndaquil, and they all agreed.
Throughout that, I was planning my final team for this file. I came up with these:
This should be a team that I will enjoy. I decided that trading for an Onix to help with Bugsy and co would be a good idea, so I'll grab a Bellsprout soon.
