2nd Gen What are your favourite events/memories from Gen 2?

From meeting the professor for the first time, to awakening the legendary Pokemon Ho-oh, there were quite a few key and memorable moments from the Pokemon Gold, Silver, and Crystal games! So on this topic, what were some of your favourite events during the game, and why?

Feel free to share anything. :]

Seeing the legendary dog trio in the Burned Tower is always a scene I remember. Also encountering Lugia/Ho-Oh.

My favourite Gen 2 memory was undoubtedly the fight against Red in Crystal, I had no idea he was at the top of Mt Silver as I was just a kid at the time and eventually managing to beat him was really great. Something about meeting this mystery trainer at the top of a mountain who turned out to be the protagonist from the last generation of games was so cool to me.
