Why is this chicken singing?

Yesterday Peter and I went up to Dublin to do some food shopping at Asia Market, the grocery that supplies most of the Asian restaurants in town. As usual I picked up a lot of Japanese stuff —
I like the “robata” style of Japanese grilling, as well as much other Japanese food — and, as usual, I picked up some things that looked interesting, though in some cases I wasn’t quite sure what they were.

This one is, as you might guess, chopped dried seaweed to be used as a garnish. Well, fine, I needed some of that. But what made me pick the package up was the chicken. She’s singing. Does it have anything to do with the seaweed? With her chicks? I have no idea. But I just love the look of some of this packaging.
