I wandered north from Pallet Town into Route 1 and I battled wild Pokemon in the tall grass in order to train my Squirtle some more. I eventually managed to arrive at my destination after about 10 minutes: Viridian City. I headed to the Pokemon Center first to heal my Squirtle who had sustained injuries in the field. Then I went over to the Poke Mart next door and I obtained Oak's parcel there. I wandered south to Pallet Town again and I gave the parcel to Professor Oak at his lab. I was given some Poke Balls before I left and I went back to Route 1. Once I was back in Viridian City. I watched some old man's Pokemon catching demonstration and I headed north to Route 2 next. I battled more wild Pokemon and saved.
