Finished All A side levels & 175 strawberries, what's more to collect?

[MelTd0wN]

i suppose i should finish all B side levels and That C side to get full achievement?
what about golden strawberries ?
i guess i can start (at least try to) collecting them after finishing C side ?
just wondering if my guessing is right

You can try golden berries in C side, they're the easiest to get.

Do golden berries after c side. There are also golden berries for b and c sides, if you didn’t know

Do golden berries last. They don't count towards 100% by the save file standards anyway.
