Dunno which category so..

"Stench of Rot" and Food rotting and turning into skulls and bones.

The Stench of rot is an item that makes the selected food rot quickly and give the Skull/Bones, but it makes all the users Lions become more hungry by 10%. (Maybe 500 in Monkey buisness)

Food rotting will turn the animal carcass into the corrasponding bone/skull (ex, hippo carcass becomes a hippo skull) and maybe a rib bone. (Wont work on snails n' stuff)

Just a random idea!
