What Are All The Pokemon You Can Find At The Poke Pelago, and Are They Shiny Locked?

Question

Out of curiosity, I want to know what Pokémon can arrive at your Poke Pelago and can they be shiny.

This is for USUM, to be exact.

This is the shiny part.  Geez, that is a big link.

Answer 1

Here is a link, that shows every Pokémon available in Isle Abeens. It should be the first big list that shows up, and shows the Pokémon, along with their "encounter rates" per island. If you'd like me to list them here, please let me know, and I will do so.

In addition, it is possible to find shiny Pokémon on the Isle, at the standard 1/4096 chance.

Here is the source the encounter odds (I just realized it's the same one as Jhnfui's, sorry about that)

And here are some sources of people finding shinies in the Isle, and people explaining how to find them:

Source 2
Source 3
