Pineapples are a miraculous fruit. Pineapples contain so much papain (aka papaya proteinase I) that it is impossible to make pineapple jello (it breaks up cholesterol, too). Imitatin pineapple jello is made with a rubbery substance. Pineapples also contain bromelain, especially at their core. Bomelain helps wounds, burns, arthritis, cancer, digestion, nasal swelling, and muscel soreness. Joke (proboscus monkeys have such a large nose, that this might help). Monkeys are known to eat who plants (leaves and all). Ditto, a group of simians might devour an entire banana tree.
