How long will it take to digest the 2 guys ?
About 5 days.
2)What parts of the young boys will it digest first ?
Skin, muscle, and fat will be digested first. Organs would be next, and bones last.
3) you said that the croc eat all that the first boy was wearing ,if that was the blue vest and whats shown in pic ,what would happen to them
They look like synthetic material, so the croc won't be able to digest them. The stomach acids will fade them and they'll look old and somewhat tattered.
4) Would the crocs digestive jucies be able to pass throu the trunks to get at whats inside them?
Yes, quite easily. Crocs have strong digestive juices.
5) once it has finished digesting the boys what all will be found in it`s poo when the scientist cleans up ,when it goes out for a breath of fresh air.
There will be the first boy's clothing, and perhaps some hair. It will look a lot like the snake poo I sent a photo of, except runnier.
6)what all did the adults fine in the pool after the attack and what will they do with it now.
They'll see blood meandering through the water, which of course, they cannot scoop out. They'll find the second boy's torn clothing. They will want to have some sort of remembrance for the boys. Since all they have is a bit of clothing, they'll build a fire, people will say some words about the boys, then they'll burn the clothing, as a sort of cremation.
