I'm aware the game is universally lambasted but I'm having so much fun with it.
I was battling some woman and a group of five smolives walked by in the background and I noticed one of them had a black olive instead of a green one. After I won against the woman I ran up to the little one with the black olive and it was indeed a shiny. I named her Madeline.
The woman in the city who rates your pokemon's size says I have the thiccest jigglypuff she's ever seen.

Sending out my tandemaus couple for the hundredth time only to find that they've started a family
is probably the most fun surprise I've ever had playing a pokemon game.
They really hit something special with this one. Yeah, I wish it looked and performed better, but it's still a hell of a good time.
