The pinecone is an inedible object found on pine trees. (Soon,) You can plant pinecones to create a random sized pine tree, small, medium, or large. They are found on large pine trees, which can be found on Acadia Mountain, and their main purpose is to supply all sizes of wood and leaves to areas where they are scarce. Pine cones will grow pine trees, which are currently the only source of large wood and large leaves on the game.
