Fallen Hollow Logs

Hollow logs could spawn in forests and could rarely spawn in the planes biome. This could be like fallen trees. Hollow logs could have two variants. One variant could be mossy, as if its been lying there (where ever it is) for a long time. The other variant could be a regular hollow log. Maybe a mob could live in the hollow logs. Such as termites, ants, or squirrels. In taigas, foxes could live in hollow spruce logs.
