Splinter's Wisdom

Character Debuts


  • Karai returns in this episode for a little moment at the beginning of the episode, until the Parasite was used on her by Baxter Fly and turning her into Serpent Karai again.
  • Serpent Karai can control her ability to shape shift, as seen when she turns her arms into snakes.
  • Serpent Karai is the only mutant so far who has been mind controlled but without the regular white eyes.
    • This is maybe because of the fact that the Parasite might of contained the Mindless Serpent Serum to turn Karai into Serpent Karai once more, since her eyes turned into serpent eyes and she was a human before that.
  • Michelangelo appears with the Iguana Puppet he found in the episode, Follow the Leader and the Troll Mask from Mazes & Mutants.
  • The movie April O'Neil and Casey Jones saw, "The Six Deadly Poisons", is a reference to the martial arts movie "The Five Deadly Venoms".
    • This was also a coincidence due to that the number of characters poisoned by Serpent Karai were six; April O'Neil, Casey Jones, Michelangelo, Raphael, Donatello, and Leonardo.
  • Casey Jones and Serpent Karai were face-to-face for the first time in a fight.
  • Casey was kissed by Serpent Karai, just in order to transfer the venom into his body.
  • Splinter is still healing from Slash's attack from Clash of the Mutanimals, when the Mind Control Serum took total control over his brain.
  • This is the first episode of the Ninja Turtles where Splinter did not break down after knowing that Karai has became part of The Foot Clan once more.
