Our babies are like penguins; penguin babies can't exist unless more than one person is taking care of them. They just can't keep going.

I'm pretty restless in bed, so I can lie there for a couple of hours and be like, 'Hey, that happened today. What if that happened at a zoo?' I'll jot the idea down. Then I'm like, 'All right, so now that it's a zoo, that penguin's loose,' or, whatever. I usually start with broad ideas.

Penguin is this interesting figure within the city of Gotham. He's this guy who has worked in the shadows and publicly. He's skirted the line between lawful and completely chaotic or villainous. He's risen and fallen multiple times in the ways that pretty much no other character can dream of.

I actually did a project with my puppet one time in fourth grade. I made up a song that went with the rhythm to a song I do now. And I had to make up a song about a penguin and research and put information in the song about a penguin. And I sang it with my duck, because I didn't have a penguin puppet, but close enough.

I think you can learn a lot from primary sources. 'The Penguin Book of Witches,' which is edited by novelist Katherine Howe, is a wonderful compilation of primary sources about witchcraft.

It's practically impossible to look at a penguin and feel angry.
