BigHorse continues to eat. His first tree is now chewed up and he gradually sends down the plant material toward his stomach. Not all of it is gone and he's already busy taking in his second tree. The horse is feeding and his passengers may do well rembering his counsil to stay on top. Otherwise they'll get burried and sent down into his gut. It won't be easy though since the fresh material is much looser than the material that's already partially processed by the stomach.
