TMNT Sezona 05: Ninja Tribunal (Izgubljena sezona)

The "Ninja Tribunal" season (13 episodes) was originally going to be season five, but the schedule was changed to try to increase interest in the series and "Fast Forward" became the fifth season to air on commercial TV. After the scheduling change was made, Mirage and its partners decided to finish production on the "Ninja Tribunal" episodes and release them directly to DVD. 4Kids Entertainment later signed a deal with Comcast and this season began airing on Comcast-On-Demand in August of 2006. Thus mass confusion has ensued regarding which season is officially season five and which is season six. However after airing 5 episodes Comcast stopped airing the episodes[1]. Fox later aired the "Membership Drive" episode on March 24, 2007, it was the first episode of the season to air on regular television.

The "Ninja Tribunal" episodes were scheduled to be released on DVD sometime in early 2007, but 4Kids Entertainment later removed them from their release schedule. 4Kids started showing the 13 episodes of this season starting on February 9, 2008. The season was promoted as the "Lost Season" The DVD set was release on May 20, 2008

Episode 06:The "Nightmares Recycled" episode was never completed. The script was finished and some animation had begun when 4Kids pulled the plug because it was deemed too controversial and violent for a children's program (Hun and the Garbageman were conjoined twins that were surgically separated at birth by a back-alley surgeon with the Garbageman being discarded as 'garbage'). Since there was no chance of it airing, it was shelved in the early stages of production.
