If only. XD; That would be too chaotic anyway, and I'd rather not lose any important school related work in a pile of junk, haha.
Heck yeah Appa. :D He was a bit off-putting as a plot device when they lost Appa in book two, though. But I still think he's awesome and that the Avatar owes him a lot! :p Azula is just someone you wouldn't expect would exist in a cartoon, but the creators are great like that. ;) The second hasn't come out yet, iirc, but I can't wait, too! I kinda wish it was still animated but it's better than nothing, I suppose.
