How could they do such a thing to him, truly they are monsters. Perhaps a slow pet down the penguin's back will make up for their transgressions, though it seems the bird's attention is still being taken up by the fish in front of him. A moment of pause is given before he polishes that third one off, at least, and he takes that moment to give an appreciative little squawk.

"We won't make that mistake again," he agrees with a tiny sigh of his own. As long as they have a say in when they leave, they'll make sure to pack lunch for everyone first!
