Sneaky Lying Cheating Giant Ninja Koopas

"Sneaky Lying Cheating Giant Ninja Koopas" is the first episode of 'The Adventures of Super Mario Bros.3'.

Plot
Inside Castle Koopa, the Koopalings are rough-housing and fighting amongst themselves. Koopa then calls the "Koopa Family Meeting" to tell them it's time for them to do something exceptionally dastardly. He orders the Goomba wearing a headband to pull a rope to open a curtain for the life-size portrait of the person they are going to attack. They did so and reveals a portrait of a extremely large Mushroomer.

Big Mouth Koopa identifies the Mushroomer as Prince Hugo, the new ruler of Giant Land, who is described as being the bravest and strongest prince ever and "even for a giant, he's a giant!". But Bully Koopa believes that Prince Hugo is not a big deal and elbows his brother to the floor; Koopa says that Prince Hugo is a big deal, but he will cut Prince Hugo down to size, by changing him into a miniature poodle with one of his wands. He asks who will bring Prince Hugo to him so that he can be transformed.

Kootie Pie Koopa pushes Bully forward but the latter says it is too dangerous and asks for a smaller prince to capture. Ignoring Bully, Koopa orders Cheatsy Koopa, Kooky Von Koopa, Bully and Big Mouth to step forward(Hip Koopa, Hop Koopa and Kootie Pie only stepped back) and zaps his wand at his four sons and transformed them into Sneaky Lying Cheating Giant Ninja Koopas. Koopa then commands his colossal children to go out and kidnap Prince Hugo.

In Giant Land, Mario, Luigi, Toad and Princess Toadstool meet with Prince Hugo and the Royal Parrot. Hugo informs them that his royal army have been defeated by the Giant Ninja Koopas and the Ninja Koopas are on their way to capture him. Mario reassures Prince Hugo, saying that they will stop the Koopalings; soon after making this remark, the Royal Parrot begins to criticize Mario and Luigi. Wanting to show-up the uppity Royal Parrot, Mario and Luigi set-off in a Warp Tube to find a couple of Super Leaves to defeat the Giant Ninja Koopas.

Outside, the Giant Ninja Koopas are heading towards Prince Hugo's castle. Exiting the other end of the Warp Tube, Mario safely falls to the ground and prepares to catch the falling Luigi. Unfortunately, Mario fails to catch Luigi and says the reason for this was that the sun was in his eyes. Insulted, the Angry Sun suddenly charges towards Mario and Luigi in rage; running from the Angry Sun, Mario and Luigi hit a nearby block which releases a Super Leaf. Touching this Super Leaf, Mario and Luigi gain raccoon powers and begin to fly through the air.

As Mario and Luigi fly, they are approached by the Angry Sun, who proceeds to ask them if they saw where Mario and Luigi went. Mario and Luigi, bemused by the Angry Sun's obliviousness, say that they went and hid behind a cloud, and the Angry Sun then flies off and begins to search for Mario and Luigi. With the Angry Sun gone, Mario and Luigi head back to Prince Hugo's castle.

The Ninja Koopas approached the castle and manage to break in. Bully grabs Princess Toadstool and Toad while Kooky and Cheatsy grab Prince Hugo. The Mario Brothers arrive and try to feebly attack the Koopalings but to no avail until Big Mouth blows Mario away and is slammed against a pipe and falls to the ground. Then the Piranha Plant appears and bites Mario's tail, causing him to lose his powers. Big Mouth grabs the flying Luigi, making him lose his powers as well.

Big Mouth grabs the Royal Parrot from it's cage and tosses it aside so that he and Bully can put Luigi, Toad and Princess Toadstool in it. As they're about to put Mario in it too, Mario jumps on the Royal Parrot's back. At first the bird would not leave it's cage behind, but eventually agrees to help Mario after Mario promises that he will get the cage back for it. The two then take off. Unconcerned with the fleeing Mario and parrot, Big Mouth says that he and his siblings should just take Prince Hugo, Princess Toadstool, Toad and Luigi to Koopa and get all their well deserved praise.

Having transported Prince Hugo, Toad, Princess Toadstool and Luigi to Koopa's throne room, the Koopalings, after being told they did a great job by Koopa, hold Prince Hugo in place while Koopa uses a wand to transform him into a poodle. After doing this, Koopa, after grabbing his "ninja wand" off the wall, prepares to change Bully, Cheatsy, Kooky and Big Mouth back to normal, but is convinced otherwise by Big Mouth, who ask if they can stay as Giant Ninja Koopas so they can conquer other kindoms. Liking the idea, Koopa puts away the ninja wand saying he will use it later. The Giant Ninja Koopas cheered and begin praising their father.

After picking up Koopa, Big Mouth and his siblings leave while Mario and the Royal Parrot, having somehow entered Koopa's Castle, approaches the cage containing Luigi, Princess Toadstool and Toad. After briefly whispering something to Princess Toadstool, Mario begins to enact a plan; going over to the rack containing Koopa's wands, Mario switches the jewels atop the wands, effectively mixing them up; after doing this, Mario hides behind Koopa's throne.

After a few minutes of mocking Prince Hugo, Big Mouth returns his father to his throne and asks which kingdom they should conquer first. Kooky suggests Water Land, Cheatsy suggests Desert Land. Koopa dismisses the two suggestions saying that he will decide which land to take over. Not before long Mario comes out of hiding and confronts Koopa, demanding him to release his friends and turn Prince Hugo back to normal. When asked what would he do if Koopa does not give in to his demands, Mario tells Koopa to let his friends and Hugo free and he will tell him next Tuesday. Koopa orders his Koopalings to grab him.

After Big Mouth grabs the plumber, Princess Toadstool says from the cage that Koopa will probably do something horrible to Mario, like turn him into a poodle like Prince Hugo. Koopa thinks it's a great idea and praises the princess for giving him the idea. He grabs the wand that he thinks is the "poodle wand", but thanks to Mario switching the wands, Koopa zaps Mario (which burns Big Mouth's fingers) and transformed him into a giant ninja, calling himself Good Truthful Honest Giant Ninja Mario.

After freeing Princess Toadstool, Toad and Luigi, Mario prepares to fight the Koopalings while his friends rush at Koopa, causing him to flee and drop his wand; as Koopa hides behind the giant Kooky, Princess Toadstool, after grabbing Koopa's wand, transforms the Koopalings back to normal as they rush at Mario. Having regressed back to normal, the panicking Bully, Kooky, Big Mouth and Cheatsy run-away at the sight of Mario. While Luigi changes Prince Hugo back to normal, the Koopalings and Koopa tremble at the sight of Mario.

As Mario begins advancing on Koopa and the Koopalings, Koopa decides to abandon his children and hits a nearby block, which causes a Warp Tube to appear out of the floor. Diving into the Warp Tube, Koopa is quickly followed by the Koopalings; after the Koopalings enter the Warp Tube, it disappears.

Prince Hugo, extremely grateful to Mario, thanks him and shakes his hand as Mario is transformed back to normal by Princess Toadstool. Suddenly, the Royal Parrot appears and begins to become extremely upset at the sight of it's cage, which was wrecked by Mario when he freed Luigi, Toad and Princess Toadstool from it. Grabbing Koopa's wand from Princess Toadstool, the parrot makes itself slightly bigger and gains ninja gear, which Mario calls Miserable Squawking Angry Giant Ninja Parrot, and begins to chase Mario, demanding he fix it's cage.

Trivia

 * The title of this episode is a spoof of Teenage Mutant Ninja Turtles; Big Mouth Koopa even spoofs the Teenage Mutant Ninja Turtles catchphrase ("I love being a turtle!") from their first film by saying "I love being a Koopa!"
 * The Koopalings also share similarities to Teenage Mutant Ninja Turtles: they are brothers, they are teenagers, they are based on turtles, they are ninjas, and each of the members' personalities reflect that of a certain turtle.
 * Bully is the team's angry member (similar to Raphael).
 * Kooky is the team's smart member (similar to Donatello).
 * Big Mouth is the team's annoying member (similar to Michelangelo).
 * Cheatsy is the team's neutral member (similar to Leonardo).
 * This episode marks the first time in the series where Koopa is referred to as "Bowser Koopa". In this case, Mario says "You're not taking over any land, you Bowser Koopa!" He is also called that in Princess Toadstool for President, Reign Storm, and Crimes R Us.
 * This is the only episode in the series to show parts of it during the credits.
 * Toad only has two lines of dialogue in this episode.
 * The only animated appearance of the Angry Sun.
