Why are hollow logs hollow? Science side explain?
A variety of reasons often related to forest fires and/or bacterial/other decay. Trees can get diseased. It may be in an environment where the inside has excess water and the outside stays dry. An animator at have chosen to draw it that way for an aesthetic effect. A hole from an amputated limb’s scar may have provided a weak spot for termites. Onamacare made the log lazy and it decided it didn’t need to work on the inside anymore. A badger rented a power auger from Home Depot and drilled the hole, then made it her den. Heartbreak left it hollow. Lightning. Sub-par quality control standards in Chinese factories. Godfarts. The middle is the oldest part.
