Plot
Finn and Jake battles a tiny ladybug so they can get it out of their home. After placing the ladybug outside, Finn closes the door and cries in pain. He finds out that the door gave him a tiny splinter and decides to get some protection for it. After getting a thimble from Choose Goose, he notices a group of Knights showing off their armors. Finn shows them his thimble which causes the Knights to make fun of him. Sir Slicer arrives and insults Finn along with the rest of the Knights. Finn then asks Choose Goose for the best armor, but couldn't afford to purchase it. Choose Goose gives him a poem which leads to the Magical Armor of Zelderon. After Finn received the poem, he began his quest for the armor. The first poem (which Jake translated) told Finn to cross a swamp (which is later revealed as the Swamp of Embarrassment). As he begins to enter, he finds that there are Naked people behind every curtains. Finn's face turns red from the encounter and meets Sir Slicer who insults him some more. After Sir Slicer left, Jake tells Finn that he must silence the strange noise in the woods. Finn finds a crying Red Faced Monster and tries to tell her to stop. The monster notices Finn and thinks that he's her baby. Sir Slicer comes back with a Lyre Player who sings a song with more insults. The monster falls asleep which gave Finn a chance to escape after Sir Slicer left. Finn and Jake then enters a cave where the Armor of Zelderon is located. There, they encounter Ghost Man who says that no one can pass him unless they beat him in a game. As he shows the instructions, Finn and Jake sneaks around him and enter the room where the Armor of Zelderon is. Finn receives the armor, but realizes that it's a girl armor. Ghost Man comes back becomes angry at them for walking out on his instruction. Jake quickly put on the armor, causing the Ghost Man to mistake him for his mom. Jake orders Ghost Man to go outside instead of staying in the cave. Ghost Man obeys and becomes alive after touching sunlight. They all cheer, but Sir Slicer comes and ruins all the fun by making fun of Finn. Finn insults Sir Slicer, causing him to get off his horse. As Sir Slicer gets off his horse, he falls over, saying that his armor is too heavy. Finn and Jake laugh at him and leave the cave.
