Someone explain this? What's it from, the comics? I haven't worked my way through them yet, except The Promise obviously.
I actually like the idea of Toph getting with an ugly person. Love is blind and all that. Why would she give a shit anyway?
It's from one of Nickelodeon's "ready-to-read" series of books, a broup of books aimed at who have recently learned how to read. IFAIK, it's has no relation to the production team of the show and they've never commented on it, so it's safe to assume they're un-canonical.
What is the target demographic? Seems like they made it everyone friendly.
While the show aims at a wide audience, Nickelodeon has a pretty low skewing target demographic. They sell the majority of their advertising time to children's toy manufacturers, so their shows aim at drawing that crowd in.
