Yeah! High level berries award you with more berries when you
transfer them to your item bag (which you can use to feed Pokemon
with). For example, 1 Level 10 Pecha berry becomes 3 feedable Pecha
Berries when transferred. The feeding rewards aren't any different,
but do note that higher level berries typically take longer to
grow. More info: https://wiki.pokeheroes.com/wiki/Berrygarden
Hello! I will always send missing plushies (unless you request
otherwise), and hope you also do the same :)
