The Turtles and their new allies find themselves in Japan, where the Ninja Tribunal reveals to them that a great evil is coming. They must all train hard to be ready for the coming threat.
This episode provides examples of
- All Just a Dream: The Ninja Tribunal's destruction, and the acolytes' beatdown, is all an illusion to teach the acolytes a lesson about perception
- Badass Family: When Splinter is surrounded by wooden warriors, the Turtles immediately jump in and form a defensive line.
- Captain Obvious: On meeting Master Splinter, whom the Turtles refer to as their sensei, Adam points this out :Adam: Dude, your sensei is a rat.
- Curb-Stomp Battle: The Akuma Toori's battle with the acolytes and the Ninja Tribunal.
- Foreshadowing:
- When Leo asks for help translating a passage in a book, Donny says it's about physically manifesting focus and energy. This will be a recurring item for the Turtles throughout the season and is immediately demonstrated by Don himself as he reads.
- When revealing their defeat was All Just a Dream, the Ninja Tribunal explains how they were challenging their acolytes' perception of the world and reality—setting up later events.
- Godzilla Threshold: The opening narration says in so many words that gathering the Turtles and the Acolytes is in response to the Foot Mystics being freed from their indentured servitude.
- "Hell, Yes!" Moment: Played for laughs when Donatello sees what the first part of their training is: studying inside a big library.
- Magical Land: This may be Japan, but as Faraji puts it:Faraji: I don't think this place is in any tourist guides.
- Series Continuity Error: Chikara-Shisho refers to the Ancient One as "Young One", revealing that the Ninja Tribunal are much older than him. However, in the Season 4 episode "Tale of Master Yoshi" she refers to him as "Ancient One".
