It is a Chestnut. If you crack it open or damage its shell in any way, its shape will begin to change—a chestnut tree will begin to grow from its body (obviously), and many chestnuts with red eyes will grow on its branches, but only one “fruit” will be without it, for it will be the future new body. The object will not remain in this form for very long, a month at most. The longer it lives in this form, the more leaves and chestnuts fall from it, and it itself becomes weaker. Well, closer to the end of its life in this form, its new body is formed, and in the end, the old body dies and the consciousness of the object moves into the new one. It becomes a small object, but in order to grow and become its age again (outwardly), it will take about a week
