evereyones always talking about Kataang and Zutara, but what about Moppa? i mean, those two are pretty much a couple... ofcourse not like ''the real people'' in this show (as long as u can call animated characters ''real people'' lol), but they do have some sort of a relationship/friendship going on. when Appa was gone, Momo responded to the word Appa (for example in ''City of Walls and Secrets''), helped Aang spreading out posters, he even dreamed about him! ofcourse they dont ''love'' eachother, but they do like, maybe even need, eachother very much. they can even talk to eachother!
i like each of those two, but together they are just hilarious!
