Climb up the wall if you can. Shimmy up the portcullis. Hell run up the wall and land on the critter. With a croc you only need a few feet. I went to a croc farm in Florida. They had these low barriers. Maybe 2+feet. But two of them about 20 ft apart so no one stupid climbed over or reached a hand in.You need to lift and find the rock before it gets to you. But I will agree that the land matters i thought they would leave you in some sort of arena.
It's a chance at least. The other three no way you make it.
