The Adventures of Super Mario Bros. 3

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 Bowser, who says that it time the Koopalings do something exceptionally dastardly. Bowser 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.

Kootie Pie Koopa is celebrating her sixteenth birthday. However, her greed has caused her to want much, much more then what she has, dissatisfying her with her presents. When her father, Bowser, asks her what she wants the most, she promptly screams "I want AMERICA for my birthday!" King Koopa is loathe to give her her wish, his reason being "But America's in the Real World!" But it's either that or put up with incessant whining, so he eventually gives in.

Hip and Hop Koopa are exploring a pyramid in Desert Hill, where they find what they claim to be looking for upon entering the pyramid's tomb, despite the fact that Bowser expected them to mess up. Startled from almost tripping on a shattered Dry Bones, Hip and Hop stumble into each other and crash into a vase, breaking it. Relieved that nothing bad happened, Hip and Hop are startled when a nearby sarcophagus starts to make thumping noises on its own. Not wanting to find out why the sarcophagus is acting up, Hip suggests that they grab the other sarcophagus, belonging to Prince Mushroomkhamen. Lifting the case up together, Hip and Hop exit the tomb with it.

One day at Castle Koopa, Bowser is sitting on his throne. He was moaning about his aching head, just as he sandwiches a hot water bottle between it and his crown. With Bowser is Kooky von Koopa, who mentions that his father seems to get headaches every time he gets defeated by Mario and Luigi. As Bowser places a second hot water bottle under his crown, he and Kooky note that he could've taken over the Mushroom Kingdom years ago, if only the Mario Bros. had never gone down the drainpipe back in Brooklyn. As Bowser and Kooky speak, they fail to notice Toad, who is hiding inside a flower pot, and spying on the duo through a parascope disguised as a flower. After some brief pondering, Kooky suggests that they can change history through the use of time travel, to which Bowser complies.

Kootie Pie is applying makeup when she hears Bowser coming to see if her room is clean. She hides the mess in her wardrobe, but Bowser is not fooled and he grounds her, only to infuriate her. Kootie Pie complains about having a rotten father, and just as Big Mouth intrudes, Kootie Pie realizes that Bowser must not be her real father. The two also decide that their father must be someone magnificent, like a movie star.

Toad is carrying a large sack with several dollar signs on it through the Mushroom Kingdom, when he places it down to catch his breath. Toad comments to himself that the next time Princess Toadstool needs someone to deliver one-million Gold Coins to the Mushroom Orphange, he'll be on vacation.

A rainstorm is currently taking place in the Mushroom Kingdom one night, and everyone appears to be confined to their homes. Princess Toadstool, Toad, Mario and Luigi are all inside Toad's House, where the Princess comments that there's been rain non-stop for two weeks while looking out the window.

Mario and Luigi are at Toad's House, watching what would appear to be a horror-themed television show, as evidenced by the heard scream, when Luigi cowers in fear of what's going to happen to the woman on TV. Mario complains about Luigi overreacting about the show, which they had brought their TV from Brooklyn to into the Mushroom Kingdom to watch. The TV is seen with a woman in front of a sink, from which some strange green slime is being produced. Luigi shouts at the woman to call Mighty Plumber, which she immediately does. Just as it looks like the slime, which has formed into a monster, is going to get the woman, the show cuts to a commercial. Mario and Luigi think about how Mighty Plumber will be able to save her.

The episode begins with Luigi finding a treasure map to the Doom Dancer Music Box. Princess Toadstool later gets Luigi, Mario, and Toad to help her get the Doom Dancer, which makes anyone who hears it dance fast or slow according to how fast it is cranked. Mario proposes that the Doom Dancer can keep the Koopa Clan under control. The group then sets out to get it in Dark Land's Temple of Gloom. When they arrive a Dry Bones hears their plans and goes to tell King Koopa at Castle Koopa. After telling him a few times (King Koopa has a cold), King Koopa sends Cheatsy Koopa, Big Mouth Koopa Jr., and Bully Koopa to get the Doom Dancer before the Mario Bros. do.

One evening in the Mushroom Kingdom, Cheatsy Koopa is climbing up the side of the Mushroom Castle, and peeks in through a window, hoping to spy on whatever Mario and Luigi are up to. Looking in, Cheatsy sees that Toad is helping Mario fit into a tuxedo, when Luigi questions why they have to wear dumb "penguin suits". Toad explains that Princess Toadstool will be all dressed up herself, but they are shocked to see that she is actually dressed to go to a rock concert, and is even wearing a jersey with "Milli Vanilli", whom she remarks is her favorite band, printed on the front. Toad comments that he doesn't understand the Real World's "weird customs", and Princess Toadstool points out that everyone at the concert will be too busy looking at Milli Vanilli to notice them. With the knowledge of Princess Toadstool going to a Milli Vanilli concert, Cheatsy retreats back to Kastle Koopa, wondering what Kootie Pie will think.
