This one has to be the hardest shiny to spot shiny for me, yet! I almost dismissed it, fortunately I didn’t blink when the sparks happened. 
Seriously… I know the nose colour is different, but only when it moved did I notice the blue on the back, instead of red. For whatever reason I thought the body would change to a different colour, as well.
I’m very happy about this one!
And not so much about this tragedy right here:
Fortunately it’s a shiny I already have (+ evolution), otherwise I’d be very upset. I can’t help but look at the journal, so maybe this tool really isn’t for me…
Two of the coolest shinies in the game, BACK TO BACK?! 
Edit: and another one, which admittedly is also an incredibly cool one (I love green shinies), even more so due to its XXL status:
Twins separated in time? 
I got the second one today in the go fest event, but I will probably evolve the 1st one all the way just because of the background. I have to think about it, I really like fennekin…
What are the odds of this? Both shiny, same stats, both male!
It certainly doesn’t. Still gives me an adrenaline rush, especially in the main series games when I find one.
