And the reasons why are hilarious (and adorable).

If you think back to your school days, you might remember a standard punishment for misbehaving consisting of extra homework or detention. But if you’re a penguin at one aquarium in New Zealand, punishment means having your misdeeds broadcast to the entire world.

In a series of now-viral monthly Facebook posts, the National Aquarium of New Zealand is revealing their worst- and best- behaving penguins in a “Naughty Penguin of the Month” board, with photos of the offender and a description of their behavior.

Exhibit A:

Transgressions worthy of the “naughty” wall have included, in the past, stealing fish, being demanding, and “being an egg-hogger and not swimming enough.” This month, a bad-behaving bird named Tux was the target for the unthinkable act of pushing “Timmy off the pier after it took him an hour to walk there.”

Exhibit B:

Some penguins, it seems, don’t learn from their mistakes. One in particular named Mo is a repeat fish stealer—earning a spot on the naughty list twice for the action—who also hoards nesting material.

But not all penguins are naughty: In addition to the monthly shaming, the aquarium rewards those who commit praise-worthy acts. In a penguin’s world, that means being a good egg incubator or standing up for a penguin who’s being picked on by other birds. And, of course, never, ever, taking a fish that doesn’t belong to you.
