On every ability where you consume food, there is a 1/1000 chance to get food poisoning from eating your food, excluding brick of course. This could award a badge but not an ability, called 'poisoned food'
Food like the moss or cobweb should have a 1/50 chance to activate food poisoning. Also if someone with a food ability is hit with any alchemist potion, the next piece of food they eat will have a 1/100 chance to die.
(This makes it easier to obtain the badge)
Im not really sure wether this is classed as a joke or low quality suggestion, i am sorry if so.
