Synopsis
When the Ice King goes away to treat a sick Gunter, Finn and Jake perform a ninja stakeout of his lair to try and find proof he's captured another princess.

Plot
The episode starts with Finn surveying the Ice Kingdom through binoculars and Jake reading a ninja manual. After stating there has been no change in 6 hours, Finn asks Flambo if "this tip is good." Flambo tells Finn he swears the Ice King is planning to nab a princess that day. When Finn starts to get restless, Jake tells him to calm down and that a true ninja can sense the intentions of his enemies. Flambo laughs and tells Finn and Jake ninjas aren't real. Finn responds by saying he and Jake are real ninjas. While demonstrating a ninja skill, Finn hears a noise coming from the Ice King's Castle. He looks up to see the Ice King pack an overnight bag and leave his castle with Gunter. Finn tells Jake the Ice King looks pleased with himself and Jake responds by saying he must have stolen a princess.

Finn and Jake sneak into the Ice King's Castle and look for the princess. When they don't find one anywhere, Finn thinks that they have stepped into a trap, but Jake states that the reason they can't find a princess is because the Ice King is doing it right now. When they go to look for proof, Jake finds the Ice King's diary and reads, "Dear Diary, and you better write me back this time! Today I'm bringing home a special new cutey." This is enough proof for them and Finn decides to hide until the Ice King comes back so they can catch him. Finn and Jake jump into the the Ice King's hamper, but after a short time, Jake complains that it reeks inside and leaves. This angers Finn to throw a meatball from the hamper at Jake, but is missed and hits the Ice King's holo-computer instead. When Finn and Jake look at it, they find pictures the Ice King drew and start to play around, until Finn accidentally knocks the computer into a thin sheet of ice, revealing a secret ninja cave. Meanwhile, the Ice King arrives in the Rock Kindom's hospital. He freezes several Rock People in order to get up to the front of the line and asks for a doctor to treat his sick penguin. Back in the Ice Kingdom, Finn and Jake look around in the cave. Jake starts to play with things and says it is too late to leave no trace. Finn finds a First Edition Ice Ninja Manual and starts to read it, until Jake steals it away. Finn suggests that since the Ice King is so into ninjas, that they are kinda lame. Jake says that they are still cool and starts to destroy things with ice nunchuks he summoned. Finn asks Jake to show him how to do that.

Back at the Hospital, Ice King and Gunter are waiting on a doctor. He suggests that Gunter make more noise, and The Ice King tells her not to oversell it. Soon, Doctor Princess walks in and starts to diagnose Gunter. He says that without Gunter, he will be all alone and starts to talk with Doctor Princess.While he is talking, Gunter starts to expand and the Ice King yells that she is embarrassing him. In the Ice King's cave, Finn and Jake are having a ninja duel, summoning different ice weapons. Finn and Jake further destroy Ice King's lair with their ninja techniques. Jake shoots an Arrow of Ice at Finn, but Finn catches it and shatters it, causing Jake to stare in awe. However, they are quickly interrupted by the Ice King returning home. Finn and Jake jump out at him to catch him with the princess, but are surprised to find him without one. Ice King tells Finn and Jake that Gunter was actually hatch and he was talking to the egg. It doesn't take the Ice King long to realize the destruction to his home, and is furious with Finn and Jake. He calls them jerks and Finn wants to make it right. Ice King tells Finn to take his overnight bag to the cage. While Finn is doing so, he hears a noise and the Ice King tells them to put it down. Finn unzips the bag to reveal that Ice King had kidnapped Doctor Princess. Ice King explains that Gunter's egg was the perfect distraction to abduct a princess. Finn, Jake and the Ice King then engage in ninja combat, with the Ice King producing a Sansetsukon and Finn and Jake producing a Shuriken and Nunchaku respectively. In the middle of the fight, Doctor Princess asks Gunter how the egg is doing, and it starts to hatch. When the egg hatches, a pink cat with a heart on its forehead comes out. The Ice King is pleased with it, and is then kicked by Finn and Jake at the same time to end the episode.
