Trivia

 * Mr Murakami was a hologram in this episode.
 * The way the episode begins with Raphael waking up in a strange room without remembering how he got there and the trap rooms monitored by Karai are homages to the terror movie franchise "Saw".
 * Mikey and Ice Cream Kitty appear playing a card game similar to the Pokémon Trading Card Game.
 * Michelangelo plays a card called "Beebobin", a bee-like creature with goggles resembling the Minions movie character, Bob.
 * Donatello's mind is trapped in a puzzle game similar to Tetris.
 * The helmet used to trap Donnie's mind is actually the top part of a M.O.U.S.E.R.S. head.
 * Mikey's trap is called "Flushomatic", a torture trap originally released as a toy in the 1987 TV series toyline, which consisted on a toilet dropping mutagen over a thread where the tortured one would be laying. See: Flushomatic (1989 toy)
 * The flushomatic was named by Rocksteady, but Mikey offered better name options like the Dump of Doom, which Rocksteady really liked.
 * Bebop and Rocksteady being the creative minds behind the Flushomatic and Michelagelo being the one tortured in it was an homage to the fact that the same thing happened in the 1987 TV series episode "Michelangelo's Birthday".
 * When Michelangelo wonders about him suffering a second mutation, he imagines himself as a female turtle which appears on screen. The female Michelangelo is a reference to The Next Mutation's character Venus, as even the pose is an homage to promotional images of the character.
