Ok, but like, just hear me out.
In terms of bonding- stuffed animals? Like, we crave affection so much that we make little fake animals to cuddle with. We use them for comfort when we're young and can even get distressed when we don't have them with us. As well as the fact that we save them and pass them on to younger generations. Even when their eyes have fallen out and all the fur is loved off, we love them, in fact, they may become even more precious at that point.
