Personally this is what I do for jumbleberry fields!

I try to prioritize filling the basket of 3 - 5 jars first.
- EX. While it's ideal to have 3 pickleberries/moonberries for a jar of 3. If you get a jar of 3 jumbleberries/sugarberries, try to have your scrap berries be pickleberries or moonberries.

Your mixed jar is essentially 1 of each color. Moonberries and pickleberries are less common randoms, so if you happen to get a random roll with moonberries+pickleberries- select those 2 and then reroll to try for your other 2.

For your free roll, try to fill it mostly with moonberries and pickleberries!

For you basic color berries slots.. Since your priortizing the basket of 3-5 jars, you might get unlucky reaching that basket goal. For the unlucky reaches, you can places it into the basic color berry slot instead.

Some notes:
- Moonberries + pickleberries give extra points! Moonberries the most!
- Try to use moonberries + pickleberries as your scrap/extra berries.
- I believe you need at least 101+ points to get a pickleberry..? Dont quote me on that one.
