unfortunately, the Nintendo Switch does not fold and fit in my pocket so I can shiny hunt on the go. also, almost every Legendary Pokémon is either shiny locked or takes several minutes of focus to just get one encounter in for a shiny hunt.
GB, GBA, and DS shiny hunting clears
in Pokémon HeartGold and SoulSilver, sometimes when you get a bite while fishing, the exclamation point will appear above your following Pokémon's head instead of yours.
this doesn't do anything at all, but I think it's kinda cute that sometimes my buddy is like, "DUDE! A FISH!"
