If you had ever watched the documentary, you'd know that Lemmiwinks must overcome many obstacles and trials to escape.

The Hero's Journey. Joseph Campbell must be proud.

If Lemmiwinks was one of these beetles he'd have simply turned around and gone out the same way he went in xD

The eventual Lemmiwinks/Wikileaks thing was freaking genius

I would imagine it also has something to do with their relative sizes, and how full the frogs digestive system was at the start.

Gives a nice mental image for "digging through shit". _Literally!_

If you get turned around and try to head in the wrong direction you just aren't going to make any headway.

Because when he's turning around, he's making his way to the head.

Experience. For some it's the third time.
