Turtles are one of the wekest animals on the planet, snapping turtles are said to be dangerouse but there is no reason to actually fear them. If you ever come across a wild snapping turtle and it is trying to hurt you the first thing you should do is stomp on it, like in Mario Brothers.

An easy thing to comapare turtles to is Hulk. Turtles are so weak and useless while Hulk is strong and useful. If turtles could become more like hulk I would actually appreciate them but until then they will remain dumb. See an image of hulk below.
Another thing that you can compare to hulk is children, children are weak and useless, much like turtles. below is an image of some children.
The only thing on earth that is equal to turtles would be a child with hulks head, it would have the stupidity of hulk with the weaknesss of a child, but since I dont have a picture of that, I'll show you the next best thing, hulk with a child's head, professionaly made by me.
