You Forgot Your Floaties

Synopsis
Finn and Jake storm Magic Man's house to rescue his new apprentice.

Plot
The episode open with Finn and Jake searching for Glob's helmet which is falling towards Ooo after the events in Astral Plane. They run toward the crash site and see a figure obsured in the smoke, already looking for the helmet. When the smoke clears, they see it is Betty taking the helmet. Wondering what is going on, they decide to follow her.

Betty enters Magic Man's house. Finn and Jake are discussing how to overthrow Magic Man and presumably rescue Betty when Magic Man appears and turns Jake into a bowl of some brown liquid and Finn into an egg (cracked, without the shell.) Magic Man puts the transformed Finn and Jake on a shelf where they will 'rule' his house while he is gone 'forever.' On the shelf is also Tiny Manticore who apparently came back after being rescued by Finn in a previous episode due to something akin to Stockholm Syndrome, as well as a photo of Margles.

Magic Man goes into his basement where Betty is preparing a transmutation wherein the helmet will combine with Betty's sweat, then Magic Man can to turn into the ruler of Mars. They discuss what they are doing and we discover Betty has been doing research since her first appearance of various different magical enitites and has found a common theme among them: Magic, Madness, and Sadness. This research has, of course, been done to find a way to save Simon (Ice King). The begin to talk in riddles about Coconut Crabs and 'Loomy Gloom.'

Then, the scene cuts to Tiny Maticore who tells Finn and Jake that they need to help Betty from Magic Man, who is using her. We see Finn as a cracked egg squeezing through the boards of his shelf to descend to the basement. He falls into a bowl of flour.

Meanwhile, Betty explains the ritual they are about to undertake wherein her human DNA will transfer through her sweat to Glob's helmet, making it into a Sorcerer's Stone which will allow Magic Man to become ruler of Mars. Magic Man asks her to make some bread with the flour which contains Finn as an egg. She does so.

At the same time, Tiny Manticore pushes Jake downstairs, and his bowl and the photo of Margles falls. The bowl tips over and Jake is spilled out onto the floor. Betty sees the spill and the photo, and takes the photo with her for the transmutation. They begin the process, while Magic Man speaks in riddles.

Betty reappears in a stark area with a mask of Margles that she puts on then takes on the total appearance of Margles. She slides into a statue of Magic Man's face. She awakes where Magic Man is speaking with a helmetless Glob who discusses that Betty as Margles is the new defence system for Mars. Glob doubts the effectiveness, but Magic Man insists saying that it's his 'tribute' since she was taken by GOLB.

Betty as Margles and Magic Man hike up to the summit of Olympus Mons. Before she can be 'installed,' Magic Man pours out his heart about how he tried to get Margles back, but failed. She then turns into a defence system, and Magic Man tries to stop the defence system realizing it was made from his nightmares.

Meanwhile, we see the bread that Betty baked has turned into a bread version of Finn (who rolls around in liquid Jake and gets him on his stomach and back) who breaks the tools used in the transmutation experiment. When all the smoke clears, Betty has Magic Man's powers and Magic Man has lost his powers. Betty sees a dark vision of a crab in a pool emerging as Simon. Magic Man says his sadness is gone, and Finn asks Magic Man to turn Finn back. He cannot as he lost his powers. Magic Man puts on Glob's helmet. Tiny Manticore begins flying Finn to Wizard City to try to find a cure.

Trivia

 * Simon says "You forgot your floaties" which is the title of the episode. Although, it is muted.
 * It is still currently unknown if Finn or Jake were turned back into there old selves however they headed toward Wizard City to do so, but they did not appear in the next episode "Be Sweet" so it is still unconfirmed.
 * However as seen in the commercials "New at 6" they are seen turned back.
 * Magic man says "You imagine the lock, before the key. You think this is a key *points to head* but it's a wastebasket!" . He later says that he went to prismo to try and wish Margles back but all that appears is a wastebasket because the only existence left of Margles is in Magic Man's mind.

Cultural references

 * When Tiny Manticore says to Magic Man "You gave me some kind of hostage syndrome.", he's most likely referring to Stockholm syndrome.
 * Betty mentions the Philosopher's Stone, a legendy alchemical substance said to turn lead into gold or to be an elixir of life.
 * The transformation of Betty/Margles into the defense system looks very similar to Baphomet, which is an important figure within the cosmology of Thelema.

Episode connections

 * Grob Gob Glob Grod's helmet is seen landing on Earth after their death in "Astral Plane."
 * Betty first arrived in Ooo in "Betty" and has been searching since to find the means to save Simon Petrikov.
 * The topic of Magic Man's relationship with Margles from "Sons of Mars" is brought up again in this episode; the incident is likewise revealed to occur prior to the incident where Magic Man ended up making Grob Gob Glob Grod's head bald.

Storyline analysis
