This is called “collective action,” and it’s very effective.

Picture this: you’re a penguin (I know, how fun!). You live a pretty normal life: walk around, swim, fall on your ass, eat fish, sleep. You know, standard penguin shit.

However, one day, you take a bite of fish and realize that something is amiss. Could it be that your zookeepers have switched your standard fish to ones of inferior quality? Of course you’d protest it!

And that’s exactly what these penguins in Japan did.
