Ninjago fans we've written our last episode, we are encouraged to know it won't be the last
Ninjago adventure. We've known for a while that after 8 great years, S9 would be our final curtain call...While we helped the story development for the lead up to the 100th Episode, it's truly the work and genius of our friend @bragischutjr. We feel lucky to be able to help pick our predecessor and we know
Ninjago is safe in his capable hands." == Release ==
