She was in surgery for the third time to get a tumor removed, and though the it was successfully removed, she died shortly after. Her just as adorable, though much less famous, sister Calliope is going to be very lonely. I ate dinner with her on my lap in her brand new rat sack, and I'm trying to give her as much attention as possible. I just wanted you to know about Penelope, because I know you two were close. -Libby, 16, Minneapolis."
