Figured some of it out, if you use the knife on the tree next to the waterfall, you get maple syrup
there are 3 gems, one in the ground on the center island, one after getting 3 charcoal from the fireplace, and one hidden in the waterfall
Finally, mushroom soup, made with 3 mushrooms, actually has big boob properties, so you just have to make that.
Took me a while to figure that out lol.
