FROG WITH OBSTACLES

A small green frog rode far away from his swamp during the night. When the day came, he knew it was time to go home. Where to ride he knows, but the trouble is, on his way a busy highway with cars scurrying back and forth, a railway with rumbling trains and a fast-flowing river with water lilies and boards. At night, when he rode, all this was not visible — there were no cars on the road, no trains were running, and now... What should I do? The frog, by the way, did not ride away alone, with his brothers and sisters. Help the poor amphibians to overcome this dangerous path and safely return to their native minks.
