I'd prefer to widen my scope though to try and get missing sleep styles.
Of the featured Pokémon, I'm missing some sleep styles for:
Squirtle - 4 star
Blastoise - 3/4 star
Metapod - 3 star
Golduck - 3/4 star
Slowbro - 4 star
Vaporeon - 3/4 star
Croconaw - 3/4 star
Feraligatr - 1/2/3/4 star
Slowking - 3/4 star
Heracross - 1/3/4 star
Delibird - 2/3 star
Cromorant - 1/2/3/4 star
By going to Greengrass, I'll forsake the Golduck and Slowing encounters in favor of Metapod and Delibird encounters. I especially want those Delibird encounters because it's the best eggs gatherer (though this might change with Cramorant).
This won't matter much, because I know I'm going to Cyan Beach for Water Week anyway.
I was hoping that Cramorant might have multiple sleep styles across different islands like Ditto does, but data-mining shows that it has just the four like most Pokémon do.
One of them is Gorging Sleep though, so we'll probably see it with a Pikachu down its throat.
