Mine was a stunfisk playing pokemon white lol. I wasn’t even too excited for it on account of that. Kinda cool I guess though since it was a random encounter.
I got really into shiny hunting and breeding come the 3ds era though. Chainfishing in X and Y was very easy to get shinies from and I bred a lot of shinies in OR/AS
Shiny popplio in ultra sun and moon, I didn’t realise it was shiny for hours bc it’s too similar to the original colours
