Episode 25, "Return of the Overlord", airs tonight at 7:30 in the US! And next Wednesday there is going to be a Ninjago marathon leading up to the series finale! All this season's episodes will air starting at 1:30 in the afternoon and continuing until the finale at the show's usual 7:30 airtime.
Also, Jay Vincent has confirmed that a two-volume Ninjago official soundtrack is planned for a worldwide release by the end of this year. Guess that's just one more thing for fans to be excited about!
