"Avatar" Book 3 to Get Extra Episode
 

AvatarSpirit.net has confirmed that the third season of Nickelodeon's Avatar the Last Airbender will have 21 episodes, or one more than the 20 episodes of the earlier two seasons because the two-part episode "Day of the Black Sun" will be considered one "chapter." They also discovered that the season finale (and, as of now, series finale) will be comprised of the last four episodes of the show.

"Day of the Black Sun" will debut in the United States this Friday, November 30, 2007, at 8:00 PM (Eastern/Pacific)
