I had to be careful. A mistake I made when I submitted ideas initially was that one of them was too much like Elephant and Piggie, thinking that was what it needed to be. That's not what Mo was looking for. But I did definitely keep them in the back of my mind. It was tricky. Like Mo Willems was saying, it had to be something that Elephant and Piggie would like to read, yet we shouldn't make anything that was too much like Elephant and Piggie, because why would you want to do that?
