Are there any secrets in new horizons? Like are there any secret ways to get free golden nuggets?

Everyone who comes to the island just tramples my flowers and asks for random stuff and I am trying everything to get Bertha to move

I need flowers, do you have colors?

On rare occasions, when hitting rocks on mystery islands, you'll receive a gold nugget. Otherwise, the only other way to obtain gold nuggets is to have someone come and give them to you.

If you need good amounts of bells, big pumpkin harvests (3 pumpkins each plant) or scuba diving (full inventory - 4 lines) are easy ways to get bells.

Thx I do scuba dive often and I fish a bunch I managed to catch a oarfish in 2 islands thanks for the help really appreciate it :)
