I planned a system... If you have a medal in your inventory(hard to craft), every time the game generate an underground village and you are near the village (~800 blocks) the game will send you a message like : "A strange voice is coming from the medal..."You will find a secret place at X Y Z" "
Mold Zombies. They attack the Gingerbread villagers, which makes the PEZ Golems attack, and if they do happen to kill a Gingerbread man, he turns Moldy and tries to attack you. (Pretty much the same actions as when a regular zombie attacks a villager)
And, cotton candy spiders? Drop cotton candy string, which could be crafted into a bow, since there's two swords but no bow.
Since gingerbread village are closed, I don't think a zombie can go there. Anyway I don't know about Cotton candy spider I prefer Cotton candy sheep.
I'm currently adding emblems to the game. They give you skills and your goal is to collect 20 differents emblems. Collecting 20 emblems will begin the end of the world. (I mean a boss... But more like a god...)
The Meaning of Life, the Universe, and Everything.
Maybe you could add it so like gummy bunnies when you kill them they could drop an edible version of them and maybe you could add this next idea i have as a drop or crafting recipe for like candy that when you eat it it can give you a potion effect based on what type of candy it is (Ex. Bunny candy would give you jump boost)
