I LOVE Momo, so I was pleased to see that, on finally getting the complete Book I DVD, that Momo gets a LOT of attention. The creators spend a lot of time talking about him on the pilot episode commentary and in the other episode commentaries. And Dee gets to comment on "The Northern Air Temple," and he gets a lot of time in the Voices of Avatar featurette. Momo's really treated as his own character.
Man, I love Momo so much . . . among the adult fans, Aang and Momo just don't get enough love.
