Plot
thumb|300px|right|Animatic Finn and Jake see sparkles on the side of the house and try to squish them. The sparkles then lead them to a Holo-Message Player. They turn it on to see that it is a message left from their dad, Joshua, who built a dungeon for them as babies, and at the end is his sword made from demon blood. The Demon appears and Joshua casts the demon away with a chant. Joshua secretly tells Jake that it's to toughen Finn up, while Finn covers his ears. Joshua explained how to get there, and also said that it would be really hard to finish the dungeon. They go some place where the Dumb Rock was, as explained in the video. They move the rock out of the way of the entrance. When they enter they're attacked by a Hot Dog Monster and a Hamburger Monster, after defeating them, they come to another prerecorded message where Joshua tells Jake to call Finn a whiny baby. They come across 2 paths, where one is a Flower Path and a disgusting monster path. They take the flower path because Jake says that the monster is "super gross". Finn kindly reassures the monster by saying "brother, you're stinky and need a shower."

In the Flower Path they find Fruit Witches, and Jake calls Finn a whiny baby. The witches try to get Finn to eat an apple, and Finn almost does, but Jake knocks the apple out of his hand and feeds it to one of the fruit witches. The apple turns the witch into a large apple and the other witches start to bite into the apple and soon try to eat Finn and Jake, but Jake farts and sends them down the wall they were all climbing. Jake tells Finn what is really happening when they go into the final passage. While Finn attempts to get the sword, Jake discovers more Holo-Message tapes. He plays the final one informing him to play it for Finn when he defeats the Giant Monster. When Finn expresses the doubt within himself because of their father's words, Jake plays the tape to Finn revealing Joshua telling Finn he made the dungeon for him as well as expressing his pride for him. Having the confidence in himself restored, he rips the sword from its place and slays the monster. They leave the Dungeon with Joshua's sword when the demon appears. Jake replays the message where Joshua cast the demon away with the spell "Kee Oth Rama Pancake." The episodes ends with the two saying their dad was 'cool.'

Trivia

 * The fruit witches resemble the girls on the title card of "Slumber Party Panic."
 * The Monster guarding the demon blood sword resembles a large Lub Glub.
 * The chant Joshua says to banish the demon is "Kee Oth Rama Pancake."
 * Thief Wizard in "City of Thieves" also chants "Pancake" three times as an incantation to turn himself into a cat, suggesting "pancake" may be a magic word. It's also a reference to Natasha Allegri's cat named Pancake.

Production notes

 * This episode was originally called "Dungeon," sharing its name with the season one episode, but it was changed to be "Dad's Dungeon".
 * Originally, this episode was going to be storyboarded by Pen alone, but Adam Muto and Natasha Allegri helped out when he didn't have enough time.

Storyline analysis

 * Jake and Finn are seen as babies at the same time. Jake's age has been said to be twenty-eight in "magical dog years," which is apparently close to thirteen in human years.
 * It is possible that Joshua died in the dungeon, as suggested by his final prerecorded message where the monster pulls him into the last chamber. Within the chamber is a video camera and pile of holo-message cartridges, which are presumably what Joshua used to record his messages.
 * However, Joshua's might not have died here, because the first flashback in "Crystals Have Power" seemed to show that Joshua was alive when Jake was older than a baby. (An explanation around this could be that it took a long period of time for Joshua to make the dungeon, and during this time Finn remained a "whiny baby" while Jake grew up faster because he was a dog.)
 * The last holo-message shows the sword missing from the mantel, possibly indicating that Joshua finished the dungeon, made it out alive, and simply bought a new camera.
 * The key to the lock around the sword was on the Giant Monster's wrist. Finn actually broke the lock instead of taking the key from defeating the monster.
 * The reason Joshua made the dungeon was because as a baby, Finn was too "soft," and cried when squeezed. Note his disapproval of baby Finn's whining in the first hologram, where he squeezes both Jake and Finn (Jake merely giggles).
 * In the last hologram before the last chamber, Joshua messages could only make sense if he knew ahead of time that Jake and Finn would have chosen the flower path. That or the other (gross) path would not lead them to the end of the chamber.
