Answer of the puzzle Give The Boy An Escape Plan is : Given Below
I think only a miracle can save the boy. What he must do is pray and wish god will save him some way.
Snack is approaching to him but I don’t think that will bite him as they are not man eater. They only bite man to survive or protect them.
Just in case if he has any smart phone and strong single around him , he can download a the sound of bullet shot this might make lion run away.
Next he can make snack fall down in water and this will definitely make those two alligators attack on snack or at least they will lose the concentrate for fraction of time. This should give time the boy jump on grand and grab the axe.
He can keep axe with him just to make sure those alligators are attacking to him again. He must remain clam as long as no rescue team is sent by Mr. Modi Sarkar 🙂
