From what I've read (I wish I could remember where), the show has been give the go ahead for at least 3 more seasons (or something like that). It is going to run beyond the originally slated end season.

 

KA, you are way off base there.
Avatar is much more like Dr. Snuggles than Teddy Ruxpin.

 

Great show, always watch it when I can but always miss the new eps. I gotta go buy them box sets one day.
