After multiple marriages have been broken up by the game, due to husbands not spending time with their wives, we now get Shiny Pokémon in Pokémon GO. That's right bitches, we can now go out on adventures with our lonesome selves and catch shiny versions of our Pokémon! Tears of joy or tears of sadness, that you are now alone, come with this update. Take it as you will..

Even more of a meh update than the previous ones. I never cared for shiny pokemon, even in regular pokemon games.

Also note that Magikarps sometimes turn into Dittos. There was been numerous of people that thought they caught a shiny Magikarp but turned into a Dittos. What trolls lol

Oh cool, I was wondering when they'd introduce shiny pokemon. I haven't found one yet though. Finding a shiny pokemon that can actually be useful in battle will be really hard.

I already have a Shiny Gyarados. 

Still have yet to randomly encounter a shiny Pokemon in the main games so I doubt this would be any different :p

Great to hear! Need more though: acessories for your Pokemon!

I want a Squirtle with Squirtle Squad shades! A surfboard for a surfing Pikachu! Get on it Niantic!
