Trivia

 * Kirby mutates into a bat in this episode.
 * This is the first time (in every version) that April stops being friends with the Turtles.
 * The ending is a homage to the Dramatic gopher (a famous Youtube video), with the 'dramatic' glare and music.
 * The device that Donatello uses to track the Kraang ship resembles the original 1989 Game Boy handheld video game system made by Nintendo. When he turns on the device, it also makes the same two tone dinging sound that the Game Boy made when turned on.
 * When pretending to be a superhero, Michelangelo called the bat Kirby "Wingnut", an homage to that character.
 * The scene when Michelangelo, Raphael, and Leonardo use the communication orb as a dodgeball is similar to a scene in the 1987 TV series episode Peking Turtle, where the turtles are playing around with a giant pearl.
 * The Cottage Cheese Demon is a reference to the movie Gremilins, where a Gremin exploded inside a microwave.
