While the Ice King takes Gunter to the hospital, Finn and Jake sneak into the Ice King's lair to find out if he's got any princess-kidnapping schemes.
"The Chamber of Frozen Blades" contains examples of:
- Battle Discretion Shot: The fight between Finn and Jake and the Ice King begins off-screen as Doctor Princess is preoccupied with Gunter's hatching egg.
- Bilingual Bonus: The Japanese symbols on the Fridjitzu Manual literally mean: "ice Ninja".
- Bizarre Alien Biology: Gunter, the penguin, gives birth to a pink cat.
- Both Sides Have a Point: Ice King has every right to be angry with Finn and Jake for breaking into his house while he was gone, reading from his diary, and violating all of his possessions. However, Finn and Jake were also right on the money predicting that he was out stealing a princess; in this case, Doctor Princessnote .
- Brick Joke: Ice King is very attracted to Doctor Princess, even though she is not actually a princess. Several seasons later, an old lost love of his turns out to look just like her.
- Casual Danger Dialogue: When Finn and Jake find out that Doctor Princess was kidnapped, upon her breaking free, she explains everything about her kidnapping in a very relaxed, uninterested tone.
- Close on Title: The title card reappears at the end of the episode over a freeze-frame of Finn and Jake kicking the Ice King.
- Comically Missing the Point: At the hospital, when an ill Gunter starts swelling up, howling with pain and looks like he is about to explode, Ice King's only response is to get angry at Gunter for embarrassing him in front of Doctor Princess.
- Eskimos Aren't Real: Flambo is skeptical of Finn and Jake's ninja skills, going so far as to say ninjas aren't real.
- Egg-Laying Male: Gunter lays an egg, which later on hatches into a floating pink kitten. Jake points out that this must mean Gunter is female, prompting the Ice King to casually check his genitalia before shrugging it off. An explanation of this could be that the Ice King has many penguin minions, and it is sometimes implied he just simply refers to the nearest one as "Gunter". Another explanation is that at least one "Gunter" is later on revealed to be an Eldritch Abomination known as Orgalorg, which of course does not have to adhere to logical biology.
- Even Nerds Have Standards: Finn and Jake wonder if the Ice King liking ninjas means that they can't be cool. (They resolve it on the grounds that the Ice King is hiding his ninja interests.)
- Gainax Ending: A floating pink cat hatches from Gunter's egg.Ice King: Gunter, why didn't you tell me?
Gunter: Wah wah.
Ice King: Oh, Gunter... - Ironic Name: Doctor Princess is not a real princess nor a good physician.
- McNinja: Finn, Jake, and the Ice King all turn out to be learning to be ninjas.
- No Ending: The episode abruptly ends with Finn and Jake kicking the Ice King while he is distracted by the newborn cat.
- Snap Back: None of the Fridjitzu techniques Finn and Jake use ever show up again. The staff said neither of them took the time to commit the incantations and hand positions to memory.
- Unwitting Instigator of Doom: Flambo was inadvertently responsible for all of the trouble Finn and Jake got into with Ice King, as he told them that Ice King was planning to steal a princess that very day.
- What the Hell, Hero?: Ice King pulls this on Finn and Jake when he tries to persuade them that they smashed up his castle while he was only taking his penguin to the hospital.
- You Keep Using That Word: A more direct example when Ice King talks to Doctor Princess.Ice King: Without Gunter, I'll be all alone! You see, I'm a widower...
Princess: Oh, I'm sorry. How did your wife die?
Ice King: Oh, uh, whah? Is that what that means?
