They are clock weights … like for a cookoo clock. They are in the shape of a pine cone, hence the lighter colored areas. From what I can see in the unfocused background, you can also see the chain that hangs down on the other side. Pull on the chain, the weight goes up and provides the tension to keep the clock/chimes/cookoo running.
Hope that answers your question.
