How to make a T-Rex eat something

Hi.

I am working on a project where the player plays as a t-rex. The t-rex asset has all the animations on itself no problem with that, licenced product. I couldn't figure out how the other object moves with and inside of the mouth.

Imagine the mouth grabs the object and after couple of chewing it swallows, like in a crocodile documentray. And i am considering to create couple of different objects for this action.

 

Place the objects you want to follow the mouth as childs object of the mouth, they should now follow the T-rex.

 

And instantiate all the new objects as child, rgiht? Because i want this mini game as an endless runner.

 

Yes, anything you want to go into the mouth, should be set as a child.

 

Ok. But this time a new question arises which is that i am going to move my t-rex in the endless run, child objects will also move as the t-rex moves. So how can i make the objects move independent till t-rex grabs them?

Is it possible to set them as child, let's say from being independet to, after OnTriggerEnter for instance?

 

I might have found a way:
1- Every instantiated gameObject will have a script which references the t-rex's mouth as parent object.
2- They will make the mouth as parent after entering the designated collider zone with OnTriggerEnter.
3- Then they will follow the mouth.
