Pakku: No.

Toph: Wait a minute...has anyone noticed that Momo is gone too?
Sokka: [horrified] Oh no....I knew it was only a matter of time! [runs to Appa] Appa ate Momo!! [opens Appa's mouth] Momo, I'm coming for ya, buddy!
Katara: Sokka, Appa didn't eat Momo. He's probably with Aang.
Sokka: [halfway into Appa's mouth] That's just what Appa wants you to think!
Zuko: Get out of the bison's mouth, Sokka.

Zuko from the play: How can you say that?! [Katara grins, and Zuko grimaces]
