Thanks for the congrats, Shdow_Chaos.
And I'm not done just yet. As I mentioned before (or at least at Serebii, sorry if I didn't mention it here), I was chaining for a shiny Electrike when I encountered my shiny Kyogre. After I caught Kyogre, I continued chaining, and just a few seconds ago, on a chain of 34, a shiny patch appeared! This is very odd because yesterday, I was chaining for a shiny Electrike, and I had a shiny patch appeared at a chain of 34 as well. I caught that shiny Electrike, and I got my chain up to 40, but shortly afterwards, my game fell out of my pocket (it was in Sleep mode), and it froze. Stupidly, I hadn't saved right after catching the shiny Electrike originally, so I lost the shiny Electrike.
But that was yesterday, and this is now. Hopefully, this shiny Electrike has the correct nature and IVs!
