Ignition Point

Synopsis
Finn and Jake sneak into the Fire Kingdom to get Flame Princess' scented candles, and end up discovering a plot against the Flame King's life.

Plot
After repeatedly releasing 'magic air' around Flame Princess, she says the smell makes her feel sad and she wants her scented candles, which are at the Fire Palace. Flame Princess doesn't want to get them because she is mad at her dad, so Finn and Jake agree to get the candles for her.

Upon sneaking into her room in the palace, they overhear a plot to assassinate Flame King using ice, however all that they are capable of observing through the crack under the door is that one assassin speaks with extended "s" sounds, while the other has an untied shoelace.They follow the voice of the former through the palace's ventilation shafts and, after being chased by a chef, disguise themselves as actors preparing to perform a play for the king. Jake devises a plan in which the two of them will mimic the assassins (Finn will have an untied shoelace while Jake will talk with elongated "s" sounds) and state their plan to kill the king with ice, in order to draw out the real killers from the audience based on their expression during the performance. This display angers Flame King, who calls the play treason. The king orders the two to be executed. However, Finn realizes that the two excecutioners are in fact the killers, as one has an untied shoelace and the other speaks with extended "s" sounds. Finn gets the crowd's attention by yelling "Naked babies!" repeatedly, and identifies the assassins. They reveal themselves to be Flame King's nephews, Furnius and Torcho, whose father the Flame King had killed in order to take the throne. They are arrested and taken away to the "punishment room." Finn then asks Flame King if everyone in the Fire Kingdom is evil, including Flame Princess. The King answers yes, but says it's possible that Flame Princess might turn good in the right circumstances.

After Finn and Jake take the candles back to Flame Princess's house, it is revealed that the Flame King is able to communicate through the candles' flames, seemingly to try to keep Flame Princess evil.

Trivia

 * This episode is the 100th episode of the show in the airing order; however, Cartoon Network advertises "The Hard Easy" as the 100th episode.
 * This is the first time that Flame Princess wears a different outfit.
 * In this episode, Flambo punched Finn and Jake to cast Flame Shield in contrast to spitting on Jake in "Incendium."
 * In the hallway of the Fire Kingdom's castle, there is a painting with the Chinese character 火, which means "fire."
 * It seems that Flame King can connect fire to fire much like his daughter.
 * The title music of You Made Me! is heard at the beginning of the episode.

Episode connections

 * The Flame Shield spell that Flambo casts on Finn and Jake is the same spell he used on Jake in "Incendium."
 * The giant lantern seen in the Fire Kingdom's castle, first shown in "Incendium," was used to contain Flame Princess and avoid a global catastrophe, as explained in "Burning Low."
 * Finn and Jake use a plastic bag from Squeez-E-Mart to hold their "magic air;" a bag from the same store was used by Lumpy Space Princess as a dress in "Gotcha!" The Squeez-E-Mart was first introduced in "Ghost Princess."
 * Finn yelling "naked babies" to get the attention of the Flame People by confusing them is similar to his strategy in the episode "Princess Cookie," where Finn screamed "Alvin's hot juicebox" to confuse one of Princess Cookie's chips.

Errors

 * Immediately after Finn slaps Jake while they are on the grass, Finn's mouth disappears for two frames.

Cultural references

 * Jake says, "Sufferin' succotash," a trademark quote by Sylvester the cat from the Looney Tunes. Jake uses the snake's hissing to create the effect of a lisp, another characteristic of Sylvester.
 * Paul F. Tompkins voices several characters in this episode. Tompkins uses the voice of his "Cake Boss" character to play the chef, and his Andrew Lloyd Webber impersonation for the theatre actor.
 * The talk about alignments at the end references Dungeons &amp; Dragons. In the game, changing your alignment causes experience penalties, and "chaotic neutral" is the alignment of rebels who are neither good nor evil.
 * The part where the conspirators talk about using ice on the Flame King 'because it'll hurt more' references a quote from the movie Robin Hood: Prince of Thieveswhere Guy of Gisborne and Sheriff of Nottingham discuss cutting Robin Hood's heart out with a spoon- "Why a spoon, cousin? Why not an axe?" "Because it's DULL, you twit. It'll hurt more."
 * This episode has several references to the William Shakespeare tragedy Hamlet:
 * Hamlet is the nephew of the traitorous King of Denmark who killed Hamlet's father, similar to how Furnace and Torcho are nephews of the Flame King who killed their father.
 * Hamlet wished to take revenge upon his uncle by becoming an actor in a play where he is able to expose the king by acting out the details of the murder and watching his reaction; however, Furnius and Torcho simply tried to kill the Flame King during the play.
 * Hamlet's father was killed by having poison poured into his ear, similarly someone attempted to pour ice cubes (apparently deadly and painful to Fire Elementals) onto the Flame King.
 * A piece of Hamlet's famous "To be or not to be" speech from Act III is heard as Finn and Jake travel through the vents.
