I have a theory, don't jack with something that can put your whole head in it's mouth and have room left over! Can't tell with no mane but I suspect the lion is a young male learning his way around. I'd also guess he hasn't met a rhino yet!
"Lord of the Jungle" just met "River God". Think how embarrassed the lion would have been had the hippo just picked him up by the head and held him for awhile! I don't see any river but I don't see any jungle either. I suspect the lion isn't going back to split hairs over whose turf it is!
