Doof Dynasty

In ancient feudal China, Princess Isabella is part ruler and Master Perry has given up the way of the warrior. After Phineas and Ferb witness Doofus Khan capture the Princess and take her as a prisoner, they track down Master Perry and convince him to teach them his warrior ways so they can rescue Princess Isabella and save China.

Episode Summary
China, 1542. A parade is going on. Buford is standing on Baljeet's shoulders to view the parade over the crowd but he finds that it is not high enough. He then discovers that due to his weight, Baljeet has fallen down on the ground and Buford is standing on his back, not shoulders. Phineas tells them that he has a better idea and they all climb on a big plank of wood. The plank begins to rise up and becomes a high wooden structure, but still Buford is standing on Baljeet, saying that his knees don't hurt when he stands like that. They see Regent Monogram and Princess Isabella in a palanquin.

The scene shifts to Princess Isabella asking Regent Monogram when she will be able to meet some local children and Regent Monogram says that it is too risky because of Doofus Khan. Candace spots the wooden structure and tries to tell Linda about it, but Lawrence Fletcher tells Linda that acrobats are on their way and so Linda ignores Candace.

The acrobats turn out to be Doofus Khan's men and Princess Isabella is kidnapped by them. Regent Monogram receives a taunting scroll which shows Doofus Khan making a face at him. General Carl asks if he should send him army to attack but Regent Monogram can't risk endangering the Princess, he wants help and laments that the Great Master Perry has retired and now resides on top of the Unclimbable Mountain of Unclimbableness and that someone should ask him for help. Phineas decides that they will go to persuade Master Perry.

Princess Isabella is brought to Doofus Khan. Doofus Khan had kidnapped Princess Isabella with the intent of making Regent Monogram too helpless to prevent Doofus Khan from taking over the Tri-Province Area. He takes Isabella up a staircase, which according to him is protected with a series of booby traps he alone knows to avoid. Ironically, he gets hit by all the traps and leads Princess Isabella, who is unscathed, safely upstairs, and pushes her into a dark room.

At the foot of the Unclimbable Mountain of Unclimbableness, Buford says that what he hates the most about the Unclimbable Mountain of Unclimbableness is that the Uncrossable River of Uncrossableness flows between them and the Unclimbable Mountain. Phineas wonders about who makes up these names and they see a man sitting under a banner which reads, "Redundant scribe of Redundantness". Ferb uses a Grappling Hook and a carriage to carry them across the river. Phineas next somehow pulls a large machine out of his small bag, and they begin climbing the mountain.

Candace follows them on foot and after several attempts, crosses the Uncrossable River and starts climbing up the Unclimbable Mountain. She calls the mountain the "Stupid Mountain of Stupidness" and suddenly the man from before pops out of a cave and states that that was what he was originally going to call the mountain. This causes Candace to stumble and fall.

Phineas and others (Baljeet, Buford and Ferb) finally reach the top and see that Master Perry is flying a Chinese kite. They tell him about the situation and ask him that why did he leave fighting. Master Perry starts a "ripple dissolve" effect, and Phineas asks what he is doing. Ferb answers that it is a "ripple dissolve" and that he must be having a flashback. Phineas wonders does he know that they cannot see it. At last, Master Perry comes back from the flashback (which is unknown to us). Phineas says that if he will not come, he should teach them some fighting tactics. They learn those tactics as the song Way of the Platypus is going on. Throughout the song, the boys are learning fighting tactics, Baljeet always messes up one or the thing they are learning.

At last, after their training is complete, the boys again climb on the giant wheel like thing and go to fight Doofus Khan. Candace appears after the boys have left and asks Master Perry about the boys. He again starts a "ripple dissolve", maybe a flashback of all the things he has done with the boys. Candace comments that she can't see what he is remembering.

The boys reach Doofus Khan's castle at last. They crash and Buford comments that Baljeet shouldn't have been given the driving. But they crash inside the castle, in front of the booby trap staircase. Phineas and Ferb dodge the booby traps and tell Buford to fight the soldiers. Phineas reaches the top and comments that it was good they had a Yak bladder. He tells Princess Isabella that they are here to save her and she should stay away from the door. Apparently, they were going to break it, but at the same moment, Princess Isabella opened the door and came rushing out. They slide down the railing and see that Buford has defeated all the soldiers. Phineas wonders how and Buford starts a "ripple dissolve" effect. Phineas says that they don't have time for a flashback. Buford says that it was not a flashback, he was just rippling because it relaxes him.

They escape with Princess Isabella, but Doofus Khan sees them and brings out his controlled robotic dragon. He goes to Regent Monogam's castle. Regent Monogram asks him what has he done with the Princess and he replies that she hadn't run away. Regent Monogram tells Carl to duck, but Carl says its a dragon, sir and not a duck. He then gets hit by the dragon's tail and then understands the real meaning of Regent Monogram.

The dragon starts burning areas around it. Suddenly, a giant terracotta warrior appears, which was being controlled by Phineas, Ferb, Baljeet, Buford and Princess Isabella. He punches the dragon and the dragon tries to burn it. But he is not burnt because he is made of terracotta. They start fighting. Regent Monogram comments that the Japanese would "love this".

Candace comes and sees the huge terracotta warrior and goes to tell mom about it. The dragon is slapped by the warrior. But the dragon tricks the warrior and pulls its key out. Without the key, the warrior tends to stop and is unable to fight. Doofus Khan's dragon picks up a Chinese house and was going to throw it on the warrior. Princess Isabella wants to know where the dragon's key is. Doofus Khan says that only a great master and warrior can know where he has hidden his key. Suddenly, Master Perry appears flying from the same Chinese kite which he was flying. He climbs in the dragon's mouth and rolls its tongue. The key is hidden under the dragon's tongue. Ferb pulls it out using a rope and Master Perry climbs out of the dragon's mouth.

The Chinese house picked up by the dragon falls on itself and the dragon begins to fall on the terracotta warrior. Phineas and others climb out of the warrior as the warrior breaks due to the dragon. Mom arrives only to a pile of rubble and tells Candace that a giant man controlled terracotta warrior is impossible because the technology is not that advanced for it. Princess Isabella meets Regent Monogram, they hug and are very happy.

Doofus Khan is given a Chinese finger trap as handcuffs, which is stuck by General Carl on his hands. A taunting scroll sticks on his head, showing Regent Monogram teasing him. Regent Monogram thanks the boys and says that there should be a system to protect them from further attacks. Phineas says that he knows what to do today. They begin building a wall by the fallen terracotta pieces. After many, many years later, an elderly Phineas and Ferb have completed building the Great Wall of China. Phineas says that it took longer than expected and Ferb states it really is a great wall. Phineas says that "what are they gonna do tomorrow?" Ferb walks away and Phineas says that he was just joking, and they should play mahjong. thumb|left|400px==Songs==

Allusions

 * The Great Khans - Doofenshmirtz's alternate name "Doofus Khan" and his character could be an allusion at the most successful Mongolian ruler Genghis Khan, or to his grandson Kublai Khan, who established the Yuan Dynasty in China.
 * Way of the Dragon - The Way of the Platypus is similarly named to Way of the Dragon, a movie produced, directed and starring Hong Kong's famous martial artist Bruce Lee.
 * The Karate Kid - The moment with Buford and the sponge could be an allusion to The Karate Kid.
 * Star Wars - When the song The Way of the Platypus is played, a Yoda like character uses The Force to lift a heavy object, just like in The Empire Strikes Back.
 * Rocky - The sequences during The Way of the Platypus are similar with many Rocky movies, specially scenes were Rocky trains to become stronger. Also the ending of Way of the Platypus is like the ending of Rocky III.
 * Power Rangers - At the end of the episode, Doofus Khan is fighting in a gigantic mecha dragon and the gang are fighting in a giant terracotta soldier. This could be an allusion to Power Rangers and the show's season two when the Megazord fights against Lord Zedd's Serpentera.
 * Platoon - The part where Baljeet throws his arms in the air during "The Way of the Platypus" is a reference to the famous scene in this movie, where Elias fell to his knees with arms in the air. This in turn was based off a famous Vietnam War picture.
 * Yu-Gi-Oh! - The door to Doofus Khan's Penthouse Dungeon looks similar to the back of Duel Monster cards seen in the Yu-Gi-Oh! anime.
 * Godzilla - Doofus Khan's mecha dragon uses Godzilla's roar when it heads to the castle.
 * "Super Mario Bros." games - The plot resembles that of the Super Mario Bros., when Mario attempts to rescue Princess Peach from Bowser. Also, the end of the episode includes a battle between the boys and Doofus Khan, much like the end of a Super Mario Bros. game when Mario battles Bowser and his minions.

To Disney media

 * Mulan- The song The Way of the Platypus may be an allusion to the song I'll Make a Man Out of You from the 1998 film, where Shang teaches an army of men to be true soldiers.
