When a word that ends with "Y" (monkey, baby, donkey, etc.) is plural (meaning more than one of the object is being described, eg. "fan" would be "fans" in plural) It ends with "ies", instead of just adding a "S" like you usually would. And when a noun (person, place, thing, or idea) that ends with "S" has an apostraphe in front
of it, eg. man's, it means the noun described is in ownership of something else in the same sentence. For
egsample," The dog's bone was hard", or "Seatlle's streets are busy".
Therfore, Berries, not Berry's.
And if you can't type "é", then just type "Pokemon". "Poke'mon" just looks weird.
