Puddle would be a shop keep
She'd buy anything.

Royal berries make queen creatures which is a breeding aid. You have to get them from Sqrawks which are little monsters.
How Royal berry works is you give it to the female. She becomes similar to that of a Bee where she will have anywhere from 10-50 eggs a day for ten in game days.
What can be done with these eggs is you can use them for ingredients. Sell them. or eat them depending on the creature.
But if you get a fool's berry, the female you breed will become independent and infertile for ten in games days. Which means the female can focus on leveling up.

And Teef wurms. A tub filled teeth.
