DAILY - GRIN - FISH
I choose a personal keyword 'fish' partly cause we already have an Umbrella keyword provided by @olgavita. I guess this pair could fit together pretty well :P
One more NB: 'grin' is a smile, but a crooked one, a bad evil smile of an evil person, or a smile of a good person that find himself in a bad, evil situation. This frozen fish has a facial expression that is far from ecstasy or bliss ... it is very likely this is precisely a dying grin. I see them on a daily basis (as I pass by this outdoors fish shop following my baby to her classes...) So, in general, the word Daily is very applicable here - the fish show me the same grin every day, they don't change it.
