Animals and the desire to leave it all behind go together like fish and ice cream!
This fish hugging his ice cream dish (if that is, in fact, what it's doing) is a perfect example. Instead of clinging to life, the fish clings to its favorite dessert... receptacle. Is that even what's going on?
All we really know is that the fish has something else on its mind besides a quick flop back into the water and the possibility of resuming a normal life.
