Sneaky Lying Cheating Giant Ninja Koopas

Sneaky Lying Cheating Giant Ninja Koopas is the first episode of The Adventures of Super Mario Bros. 3 and, thus, its series premiere.

Plot Synopsis
Inside King Koopa's castle, the Koopalings are rough-housing and fighting amongst themselves. Eventually, the Koopalings are called into attendance for a "Koopa Family Meeting" by Koopa, who says that it's time the Koopalings do something exceptionally dastardly. He goes on to tell a nearby Goomba wearing a headband to to pull a rope to open a curtain to show the life-size portrait of the person they are going to attack.

Once the curtain is moved aside, a picture displaying an extremely large Mushroomer is revealed; Big Mouth Koopa identifies the man as Prince Hugo, the new ruler of Giant Land, who is described as being the bravest and strongest prince ever and "giant, even for a giant." A vain Bully Koopa says that the prince is no big deal and elbows Big Mouth to the floor; King Koopa begins to say that Prince Hugo is a big deal, but he'll cut Hugo down to size, by changing him into a miniature poodle with one of his wands, but he'll need a volunteer to get Hugo so he can be transformed.

A panicking Bully is suddenly pushed forward by Kootie Pie Koopa. As Bowser prepares to zap the protesting Bully with his wand, he orders Big Mouth, Cheatsy and Kooky Von Koopa to step forward. As Kootie Pie, Hip and Hop Koopa back away, Bowser zaps Bully, Cheatsy, Kooky and Big Mouth with his wand, turning them gigantic and inexplicably giving them weapons and ninja costumes. Bowser then commands his colossal children to go out and kidnap Prince Hugo so he can conquer Giant Land.

In Giant Land, Mario, Luigi, Toad and Princess Toadstool are attending a meeting with Prince Hugo and his parrot. Asking Prince Hugo why he called this meeting, Prince Hugo says that his armies have been defeated by the giant-sized Koopalings and that they're now coming for him. Mario reassures Prince Hugo, saying that they'll stop the Koopalings; soon after making this remark, Prince Hugo's parrot begins to criticize Mario and Luigi. Wanting to show-up Prince Hugo's uppity parrot, Mario and Luigi set-off in a Warp Tube to defeat the Koopalings.

Outside, Big Mouth, Cheatsy, Bully and Kooky, while rampaging through Giant Land, begin to head for 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. After saying this, Mario and Luigi are suddenly attacked by the Angry Sun; 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 to Prince Hugo's castle.

The Koopalings, having reached Prince Hugo's castle, begin to try and break into it. Managing to do so, Bully and Big Mouth proceed to grab Toad and Princess Toadstool, while Kooky and Cheatsy grab Prince Hugo. As the Koopalings prepare to leave, Mario and Luigi appear and begin trying to feebly attack the Koopalings. Big Mouth, annoyed, easily defeats Mario by simply blowing him away.

Crashing to the ground, Mario is bitten by a Piranha Plant and loses his Raccoon powers; Luigi also loses his powers after being jabbed by Big Mouth, who grabs the now powerless Luigi. Opening the cage of Prince Hugo's parrot, Big Mouth roughly grabs the bird and tosses it aside so he and Bully can place Toad, Luigi and Princess Toadstool in the cage.

As Bully begins to try and grab him, Mario leaps onto the back of Prince Hugo's parrot and tells it to fly away. At first the parrot is hesitant to leave without its cage, but it finally does fly away when Mario promises to eventually get its cage back. 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 Bowser and get all their well deserved praise.

Having transported Prince Hugo, Toad, Princess Toadstool and Luigi to Bowser's throne room, the Koopalings, after being told they did a great job by Bowser, hold Prince Hugo in place while Bowser uses a wand to transform him into a poodle. After doing this, Bowser, after grabbing a wand off the wall, prepares to change Bully, Cheatsy, Kooky and Big Mouth back to normal, but is convinced otherwise by Big Mouth, who says with their new size and skills, conquering other kingdoms will be easy.

After picking up Bowser, Big Mouth and his siblings leave while Mario and Prince Hugo's parrot, having somehow entered Bowser'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 Bowser's wands, Mario switches the jewels atop the wands, effectively mixing them up; after doing this, Mario goes back into hiding in the shadows.

After a few minutes of mocking Prince Hugo, Bowser is returned to his throne by Big Mouth and begins trying to think of which kingdom he should have taken over. After ignoring suggestion from Cheatsy and Kooky, Bowser is suddenly approached by Mario, who demands that Bowser releases Princess Toadstool, Toad and Luigi and that he change Prince Hugo back to normal.

Bowser, believing Mario to simply be bluffing, asks what he'll do if he doesn't give into his demands. Mario tells Bowser to let his friends and Hugo free and he'll tell him why next Tuesday. Bowser has Big Mouth grab Mario. Princess Toadstool says from the cage that Bowser will probably do something horrible to Mario, like turn him into a poodle like Prince Hugo. Thinking that to be a great idea, Bowser grabs a wand of the wall and zaps Mario with it; thanks to Mario's tampering with the wand though, the wand burns Big Mouth's fingers and causes him to drop Mario; landing on the ground, Mario transforms into a gigantic, ninja version of himself.

After freeing Princess Toadstool, Toad and Luigi, Mario prepares to fight the Koopalings while his friends rush at Bowser, causing him to flee and drop his wand; as Bowser hides behind the giant Kooky, Princess Toadstool, after grabbing Bowser'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 Bowser tremble at the sight of Mario.

As Mario begins advancing on Bowser and the Koopalings, Bowser 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, Bowser 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, Prince Hugo's parrot appears and begins to become extremely upset at the sight of his cage, which was wrecked by Mario when he freed Luigi, Toad and Princess Toadstool from it. Grabbing Bowser's wand from Princess Toadstool, the parrot makes itself slightly bigger and gains ninja gear and begins to chase Mario, demanding he fix his cage.

Trivia

 * The title of this episode is an obvious 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're brothers, they're teenagers, they're based on turtles, they're ninjas, and Bully is the team's angry member (similar to Raphael).
