Well I found my old gameboy advance and I found my old gold game that I got long time from my bro
so I got to lake of rage headbutted the tree and a sleeping spearow comes out!
Was it night time? Spearow and a lot of Pokemon are asleep when they get headbutted out of a tree at night, just like you can find sleeping Hoothoots and Noctowls during the day.
