Quote: I don't know if this is true anymore, but there is/was a chance of not getting the disease when you eat Poisonous Jelly. Everytime my pet eats it, nowadays, he gets Neomonia.
I believe it's not 100% guaranteed to give you an illness, I've manged to feed my pets the poisonous jelly and them be fine but more often than not they get sick so I generally just discard them now
