Mom: You've had Peanut for a long time, haven't you?
Ellery: Yes. I think since I was four. And now Peanut's cousins live with us too. I don't know why.
Mom: Her cousins live with us?
Ellery: Yes. Her whole family does. Well, not her mom and dad. Her mom lives in Hawaii and her dad is fighting in the war between the mice and the rats.
Mom: Oh my!
Ellery: Actually the mice already won the war. If they had lost, then all of Peanut's family would have to go live with the rats. But since the mice won, they got all the rats' stuff. Now Peanut's family is rich!
