Help Creating Collapsing Rigidbody

Hi! I’m currently trying to make it so mobs in my game fall apart with physics when they die. In essence I want all my mob to be made up of one entire rigidbody when it is alive, but when I remove the parent gameobject holding the creature in shape, the individual limbs and parts of the creature break down into their own Rigidbodies.

I imagine there’s some elegant solution to this issue that someone would be able to explain to me. Ideally I’d like to make it so the parent’s rigidbody overwrites its children’s rigidbodys, but I’m not sure this is possible and as such i’m looking for an alternative.

If you have mobs, that won’t change, one option is, that you create two prefabs, 1 with one rigidbody and 1 with multiple rigidbodies on every single bodypart, and when the first dies, he instantiates the second and deletes himself.
