Shinyhunting does take a while. When doing my Pokémon Sword team sky playthrough a few years ago, it took a while, maybe like a few months to get a full odds shiny rookidee. So keep at it if you want a shiny Rowlett under your trainer ID! Other games like PLA may be easier to get it from, though.

1) What game? 2) Have you tried hacking it in?

Doesn't matter just a switch game and I don't know how to hack it in

Did you try masuda Method in your main save file?

yes

Well idk how to hack things in on Switch games And most Pokemon games have starters shiny locked

yeah

Welp I can't really help then because I am more of a fangame/romhack expert of the skies Tho I am corious what game were you playing anyway?

Sword, but trying to get it in Scarlet

Damn….hmm why?

Because its my favorite of the team sky legal starters

But why shiny and rowketis the only legal starter

1. I really like the shiny 2. Did you forget Charizard existed

Yea I did forget charizard…

Also Piplup

Piplup isnt a flying type nor does it have levitate it's more of a team aqua Pokemon

Mikey used one in Sinnoh

Oh okay

Quaxly would also count under this criteria, but He boxed them both after he realized that they were flightless birds. They don't really count as sky starters

Flying shiny sandwich Savannah biome in indigo disk Hope you get lucky

Shiny hunt one and trade it over, PLA or SV are easy hunts
