In the wild, chimpanzees will store chewed up fibrous materials (called a wadge) in their bottom lips. This way they can suck every last bit of juice out of tough, chewy plants. Just like their free-living counterparts, the Cle Elum 7 wadge fibrous things such as alfalfa cubes, pine tree needles, cattail leaves and other edible plants. They seem to enjoy eating their dry primate chow this way, stuffing their lips full and adding water so they can slowly savor the flavor.

A juicy wadge of pineapple peel sounds prickly but fun.
