Berlioz, Michael Darling, and Alice (Disney's Aristocats, Peter Pan and Alice in Wonderland) are Ser Pounce, Tommen, and Myrcella Baratheon-Lannister (Game of Thrones)
Myrcella and Tommen were difficult. I thought about Alice or Wendy for Myrcella. Wendy works with Michael because they're already siblings but Alice looks better as Myrcella. I don't really know a great deal about Myrcella since she's in Dorne for most of it. Michael Darling is Tommen because both are sweet young boys, although I would have liked it if he was a bit older.
And I really wanted to put a kitten in there for him so Berlioz from the Aristocats.
