Human of wood

A new being that can be camouflaged in fir, jungle, savanna, birch and oak trees. It would have the texture of the tree in which it camouflages itself, and when it sees you it will start attacking you. When he dies, he will release the wood in which he was camouflaged. It could have a human form or any other. This being would appear at any time, like creepers and spiders. When running I was able to leave wooden blocks made and not made.
