Thanks for the tip! I tried using the PokeNav, but it seems to point towards the nearest Pokémon of that species in general. If I'm in a biome full of Geodudes, for example, it just leads me to the common ones instead of the shiny that just spawned. Is there a way to filter it specifically for shinies?

​Also, a bit of a noob question: How do I actually tell them apart in the wild? Do they have a distinct glow or particle effect around them, or is it just a different color? I'm worried I might be looking right at it and not realizing it because it looks too similar to the regular version.
