  • The characters (氷忍者) on the manual literally mean "ice ninja" in Japanese.
  • The entire concept of "fridjitzu" is most likely a reference to Naruto, specifically Haku's Ice Style ninjutsu.
  • Despite Ice King needing the crown to give him power over ice, it would appear anyone who learns these moves can create ice, such as Finn and Jake after studying it.
  • After "The Chamber of Frozen Blades," Finn and Jake have not been shown using techniques that they have learned from the manual, probably because they could not be bothered to commit the incantations to memory.
  • Jake was holding an ice kusarigama (a weapon with consisting of a sickle attached a chain with a weight on the other end) and Finn is holding a large ice shuriken and sword when the Ice King discovers them.
  • The word "Fridjitzu" is a portmanteau of "Frigid" and "Ninjitsu."
  • It seems to have some resemblance to Sun Tzu's "The Art of War," an ancient book of different war strategies.
