Skeletons divided into pieces in the taiga and dark forest

During the day in the taiga and the dark forest there are skeletons on the ground divided into different pieces (head, right arm, left arm, torso, right leg, left leg). There are collectibles inside the head and torso (copper, maps, bottles, gold). When the sun goes down they have an animation that will bring all the pieces closer to the torso and rise from the ground so the day with a 15% probability will break when falling, the remaining 85% will burn when they are exposed to the sun, when they are not exposed they have the 100% chance it will break when falling to the ground. Please add it thanks.
