Yesterday I fish chained for Staryu but instead found another 2 Clauncher's, the first was at 232 and the second at 18...
Today I found a shiny Slugma in FS at 75 encounters.
Edit: WOOOOOOOOOOO!!!!!!!!!!!!!!!! I'm dexnaving for Growlithe on Mt. Pyre, I also encounter any Vulpix that pops up as well as the other Pokémon, just got my second shiny Vulpix, only 9 Vulpix encounters from my 1st one. I previously did well over 1500 encounters for a shiny Ninetales in Friend Safari and ended up getting 3 shinies but not Ninetales, then the first Vulpix took 599 dex nav encounters, really happy this appeared 9 Vulpix encounters after. It's holding a charcoal too so free 5,000 dollars.
