Real Viridian Forest should exist in your head. I know that kids nowadays have no imagination but try to grind your braincells against each other just once.
In RBGY it was big, wast, scary and full of dangers and full items because you as a trainer was weak and there was plenty of other kids running and collecting bugs there.
In GSC you visit Viridian Forest when you are Pokemon Champion, with no little bugs and birds being even remarkably threatening to you. Also during 3 years between RBY and GSC most kids grew up, moved from chasing bugs and get assimilated into more and more industralized life of Kanto. Maybe bug catcher from RBY is now some fag NPC in Janine's gym, cosplaying as her?
