Plot
thumb|300px|right|Animatic Finn and Jake see sparkles on the house and try to squish them. The sparkles 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 (Finn was covering his ears) it's to toughen Finn up. 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, were 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. 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 the go into the final passage. Where Finn thinks he's too whiny to fight the last monster. Jake plays a rap version of the last message while Finn defeats 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 a chant.

Trivia

 * This episode was originally called "Dungeon," sharing its name with the season one episode, but it was changed to be "Dad's Dungeon".
 * The Snail was seen in the preview of this episode.
 * The scene of the witches telling Finn and Jake to eat the fruit has some resemblance to the Biblical story of Adam and Eve, or the island of the lotus eaters from the Odyssey.
 * Finn gets a new sword this episode, his father's, which is made out of demon blood.
 * The fruit witches resemble the girls on the title card of "Slumber Party Panic."
 * The black creature on the witches heads some-what look like Lub Glubs.
 * The chant Joshua says to banish the demon is "Kee Oth Rama Pancake."

Storyline analysis

 * Jake and Finn are seen as babies at the same time, even though Jake is twenty eight. However this can easily be explained that Jake is a magic dog, so twenty eight in magical dog years may not actually be much older than thirteen in human years. It is also possible that Jake, being a magical dog and not a human, simply grows and develops at a different rate than Finn, allowing him to retain an infant-like appearance/size in the hologram scene despite not being an infant, himself.
 * 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, this may not be the cause of Joshua's death, because the first flashback in "Crystals Have Power" seemed to show that Joshua was alive when Jake was older than a baby.
 * It could be possible that it took a long period of time for Joshua to make the dungeon over the period of years, putting aside time to be a father and to train his natural sons Jake and Jermaine. However, if he did make the dungeon in a short period of time, it could explain why he believed Finn was a "whiny baby": with the passage of time faster for dogs, Joshua would not have seen Finn grow up to become the hero he eventually became and would merely remember him for the baby and toddler years where he found and raised him before his eventual death.
 * However in The New Frontier Jake remarks that he could possibly live for another century, so prehaps time does not pass at different rates for Dogs.
 * 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.
