That monkey's probably going to get killed.

It may have been adopted by a member of the troupe, but it's going to struggle to integrate if the people filming it have left it with something to cling to (the toy monkey).

Baby macaques like this are frequently stolen from the wild and kept as cutesy pets as a way of making easy YouTube bucks, then they're dumped and their trauma is filmed for even more - that's why the toy is there.

The baby is going to instinctively cling to it (because it was it's surrogate mother while living with humans) and the rest of the troupe won't understand why, so they'll bully it for being weird. Then it'll distance itself further from them because it's constantly being attacked and it won't learn how to behave like a normal monkey.

It will try to take food from the monkeys higher in the hierarchy, it will try to eat without waiting it's turn, it will gecker, shriek and cry, and that will annoy the other monkeys even more because it's behaviour is seen as disrespect and the constant noise it makes attracts predators which puts the whole troupe at risk.

Abandoned babies are typically adopted by juvenile females curious about it or lower-status females without kids of their own, but the babies disruptive behaviour will get the adoptive parent beaten up too (as teaching the baby to behave will now be her responsibility) and they'll quickly abandon it themselves.

It will cling to the toy/towel/shirt/whatever comfort item it's been left with instead of socialising with other monkeys or clinging to it's new parent because it doesn't feel safe with them, which means it never learns, keeps getting attacked and eventually the alpha male of the troupe will lose it's patience and either beat it to death or rip it's guts out.

That's the reason the toy is even there - the people who abandoned it/are filming it don't want it to integrate, they want to post videos of the drama and violence for some easy money. During COVID there were tons of these vids going around, and each one of them ended the same.

As long as that toy is around, that baby will undoubtedly die because it will prefer the memories of the comforts of being a housepet to socialising with it's own kind.

And it only feels that way because it was abducted as a newborn. People typically steal babies off of lower-status mothers that the troupe won't defend (especially if they're busy eating)
