Poke Pelago in "Pokemon Sun and Moon" is an excellent way to obtain shiny Pokemon without the use of traditional breeding methods. Apart from the SOS, Gen VII introduced this method and it reportedly does not require much of an effort to catch the shiny Pokemon. The small group of islands that make up Poke Pelago are unlocked as soon as a player completes the Kiawe's trial.
As per iTech Post, "Pokemon Sun and Moon" players will receive Poke Beans and probably new shiny Pokemon once they get to the Isle Abeens, which is the first island. However, players need to do certain things before they get their hands on shiny Pokemon. Firstly, they need to upgrade their island to Rank 3. To accomplish this, players need 90 plain Poke Beans and 30 Pokemon in PC box.
Leveling up the island in "Pokemon Sun and Moon" increases the supply of Poke Beans and more Pokemon visit players. This in turn increases the chances of encountering shiny Pokemon. Pokemon are attracted towards the Poke Beans. Hence, players must put as many beans as possible to attract maximum number of Pokemon.
After this, all players need to do is wait. Log out and log in once again to check whether any shiny Pokemon has come to visit the island or not. Pokemon start visiting even if there's only one Poke Bean in the island's cart, near the tree. Many "Pokemon Sun and Moon" playershave found shiny Pokemon this way, though at first it may seem this is an excruciatingly long and time-taking process.
Uncertainty is always there in the "Pokemon Sun and Moon" game and there is little guarantee the Pokemon a player finds will join his/her party. The Pokemon may just leave after sometime though it will be back sooner or later.
