Reptiles in the Rose Garden
In Reptiles in the Rose Garden, Mario, Luigi, Princess Toadstool, and Toad see King Koopa's Doom Ship flying to the real world. However, King Koopa uses Chain Chomps to capture them. The reason King Koopa is heading to the real world is that it is Kootie Pie Koopa's 16th birthday and she wants America for her birthday. The Doom Ship arrives at Washington, D.C. to kidnap the President by beaming up the White House. Kootie Pie then announces the new "laws" over the U.S. In order to escape, Princess Toadstool makes the Fire Brothers fight the Boomerang Brothers while using their firing from them to break the Chain Chomps' chains. The Doom Ship beams down the White House into the Mushroom Sea where the President may never be rescued.

Mario, using his frog suit, swims to the bottom of the ocean while avoiding many obstacles to the White House. Mrs. President, who mistakes him for for a member of the Secret Service, greets him. Mario goes to the basement and uses a value that raises the house to the surface.

However, the Sledge Brothers are not fooled. Despite this, Mario and Luigi manage to enter the engine room to control the Doom Ship. Mario first beams down the White House on top of the Washington Monument by mistake, but he quickly corrects this.

The Beauty of Kootie
Mario and Luigi in The Beauty of Kootie arrive in the Sultan's palace located in Desert Land. They need to fix the bath tub, which has oil flowing into it. The Sultan's palace is located over an oil well. The oil flowing into the bathtub is a result of crossing pipes between one that leads to the Sultan's oasis and another that leads to his oil well. Cheatsy Koopa and Kootie Pie Koopa are behind this, fueling their Doom Ship with the oil and using pipes from the oasis. Before the Mario Bros. arrives, Cheatsy comes with a plan that transforms Kootie Pie into a human to distract Mario. However, the transformation is not perfect because Kootie Pie's tail is still present. Kootie Pie quickly hides her tail, but Luigi detects it before it is too late. Mario falls in love with Kootie Pie's human form, which Kootie Pie refers to as "Lady Fettuccine Alfredo".

Lady Fettuccine tells everyone to come in the basement in case the palace may explode. The Sultan, the guard, Mario, Luigi, Princess Toadstool, and Toad are led in the basement, but Lady Fettuccine quickly locks them in. She demands Cheatsy to return to her original form. When Mario realizes that Lady Fettuccine is Kootie Pie Koopa, Kootie Pie sprays them with oil. Mario and Luigi open a Warp Pipe and escape the basement. While Kootie Pie is taunting the prisoners, Mario and Luigi took Cheatsy's wand and transforms Luigi into a Koopa who refers himself as Casanova Koopa to deceive Kootie Pie Koopa. Kootie Pie, deceived, frees the prisoners and makes a living room for her and Casanove Koopa. However, her wand is accidentally activated, reverting Casanove Koopa to Luigi. Kootie Pie and Cheatsy, outraged, chases Luigi upstairs. Mario sprays the Koopalings, King Koopa, and his minions oil. Princess Toadstool stops the King Koopa and his Fire Chomps by spraying water.

Princess Toadstool for President
Mario, Luigi, and Princess Toadstool in Princess Toadstool for President while fishing sees Toad running to them and saying that King Koopa has brought a Paragoomba swarm to Mushroom Kingdom. King Koopa intends these Paragoombas to eat all the crops in Mushroom Kingdom so the people in Mushroom Kingdom have to pay for his food. After Mario and Luigi defeats these Paragoombas, Princess Toadstool suggests that King Koopa should run an election if he has such a lust to rule the kingdom. Much to Mario's shock, King Koopa agrees. Later, mysteriously, Mario and his gang observes King Koopa in the parade, tossing out gold coins as freebies. When Mario and gang are in Toad's House, Mario and Toad are suspicious of King Koopa's nice behavior. They worry that it may help him win the election. Princess Toadstool argues about the incident at Mushroom Kingdom Founder's Day Picnic.

At the picnic, Mario and Luigi stare in shock while a firecracker sets off during Princess Toadstool's speech. The mountain of blocks collapsed after the firecracker explosion and Princess Toadstool seemingly jumps off a cliff. Later, Mario and Luigi discovers that she is hiding in a Warp Pipe. Later, Mario and Luigi spies on King Koopa, whose nice status is wearing off. Here, they discover how King Koopa became so nice: Kooky von Koopa has made the Nice Guy Potion to make King Koopa nice. Mario and Luigi follow Kooky and King Koopa's destination in Dark Land. They manage to avoid Rocky Wrenches and Tanks by jumping in a Warp Pipe, but they end up in a pit with Fire Chomps, Hot Foots and a Fire Snake. Nevertheless, they make it to the other side. Mario and Luigi arrive at Kooky's lab, located in Castle Koopa, where Kooky is preparing more Nice Guy Potions. Luigi distracts Kooky while Mario dumps the formula in the drain. Mario and Luigi escape before Kooky and Cheatsy can seize them. During the election, Princess Toadstool accuses King Koopa of using a Nice Guy Potion, but King Koopa denies it.

Never Koop a Koopa
In Never Koop a Koopa, Mario, Luigi, Princess Toadstool, and Toad notice King Koopa and the Koopalings announcing that he is giving up by holding a white flag. King Koopa says that he is renouncing his evil ways and leaving the Mushroom Kingdom forever. He gives Princess Toadstool a key to his castle and leaves via Warp Pipe. Princess Toadstool wants to make the castle a place for elderly people, but Luigi warns her that it is a potential trap. Princess Toadstool objects and goes anyway, while Mario, Luigi, and Toad follow her.

When Mario and Princess Toadstool walk in the castle, Mario is suspicious of the place due to the falling Dry Bones and the moving eyes of the King Koopa portraits. Suddenly, the doors close and several Thwomps and Ptooies attack them. They manage to escape the ambush, but they fall in a trapdoor leading into a dungeon. King Koopa tells Princess Toadstool to sign a contract to give up the kingdom, but she refuses. He threatens her by dropping many Bob-ombs in the dungeon. Eventually, at the threat of blowing up, Princess Toadstool agrees, but only if she gets moved to the throne room and only if King Koopa wears something formal. The Sledge Brothers then toss, Mario in a wardrobe along with Luigi and Toad, who were caught previously while investigating the castle. Princess Toadstool then draws a goofy faceconveying signing the contract under the threat of her friends being trapped in the dungeon again.
