Berries

Taking Berries Into Hive/Leaving Hive Logic
If you supply the hive with a berry, you come out of a random hole each time. It is not based on adjacency or any other rules other than random number generation as far as we are aware.

The same goes for The Split Juniper map, where you may come out of the top or bottom. It appears random, with the exception of course that if there are no open holes on bottom, you will always come out on top, and vice versa.

Do berries count when you throw them in?
Yes, throwing counts for berries. You know how it has a flashy trail behind it? As long as it has that, it counts, even if it rebounds. The only time it doesn't is when they get kicked or boinked around. Even if you're the one responsible, it won't give points.

If a queen hits a berry into a hole, will it count towards their berry stat?
Yep!

Do berry bushes eventually grow back?
Nope, see berry famine.

Is It Berries or Beans?
Grapes.

Just kidding, they're berries per the developers.
