"I know when my friend Appa -- he's my sky bison -- was stolen, I acted really angry, because I was sad and scared too. Appa's been with me for years, and he and Momo -- Momo's a flying lemur -- are the only others from the Air Temple where I grew up. And it was easier to be angry and strike out than worry about what was happening to Appa and if he was safe, even if it really scared my other friends."
