 Plot Synopsis
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.
Upon Cheatsy's return to Kastle Koopa, Kootie Pie is throwing a temper tantrum because Princess Toadstool can go to concert, while she can't. After throwing some random objects at Bowser, Kootie Pie screams until he gives in, and even offers to let her keep Milli Vanilli as well. When Kootie Pie runs off to change into a dress, Cheatsy comments that he can't wait to see Bowser pull off his plan, only for Bowser to order him to fire up the Doomship, and that he must come along.
At a stadium in New York City, which has been set up for the concert, Milli Vanilli run onto the stage, introduce themselves, and toss a rose into the audience, which Princess Toadstool catches. Mario and Luigi can't stand the screaming audience, and cover their ears. Milli Vanilli then begin to sing "Blame it on the Rain". After a while, the Doomship flies over to the stadium, and Bowser fires a beam at part of the stage, lifting Milli Vanilla up into the air with it. Soon Milli Vanilli disappears, and Bowser laughs as the Doomship warps away. Mario tells his friends that they need to head to Kastle Koopa as soon as they can in order to save Milli Vanilli, and they prepare to leave.
At Kastle Koopa, Milli Vanilli is reluctantly introduced to Kootie Pie. She develops a crush on Rob, and Kootie Pie kisses him several times, which disgusts him. Rob and Fab try to leave, but Kootie Pie tells them that they can't, and demands for them to perform a private concert just for her right away. When they refuse, Kootie Pie pulls out her Magic Wand, and threatens to transform Rob and Fab into a pair of accountants, to which the two laugh "Accountants? That is a good one!" Annoyed, Kootie Pie makes good on her threat and transforms Milli Vanilli into accountants, to which they shout out "No! We are geeks! We are dweebs!" Fab tells Kootie Pie to turn them back to normal, but Kootie Pie that they're stuck in Dark Land forever. Rob and Fab try to escape, but two Sledge Bros. block the exit.
Kootie Pie threatens to turn Rob and Fab into Beetles if they refuse to perform a concert, and Fab questions why anyone would not want to be a band from the sixties. Kootie Pie then considers turning them into Ptooies, but Rob has never heard of a band by that name. Fab tells Kootie Pie that they are unable to perform a concert without a backup band, so Kootie Pie remarks that they have to stay as accountants until they can find one.
Princess Toadstool, who is spying into Kastle Koopa through a window with her friends, explains that she'll never hear her favorite music again if they can't get Milli Vanilli back to normal. Mario reassures Princess Toadstool that they'll save Milli Vanilli from Kootie Pie, but Luigi questions how. Mario then remembers Fab's remark about needing a backup band, so he decides that they should pose as one.
Dressed as a rock band, Mario and his friends enter Kastle Koopa through a Warp Pipe, and head for the throne room, while Kootie Pie throw a temper tantrum about how Bowser forgot to bring her a backup band in addition to Milli Vanilli. After Mario's group arrives, Fab recognizes Princess Toadstool from the audience at their concert back in New York City, and she whispers that they're here to save them. Mario introduces his group to Kootie Pie as the traveling backup band "Backups "R" We", whom Kootie Pie is thrilled to see have arrived so suddenly. Princess Toadstool asks who will sing while their group plays "...these two accountants?", and tricks Kootie Pie into turning Milli Vanilli back into their usual selves.
With Rob and Fab restored, Rob tells Mario to play "Girl You Know It's True". However, Mario and his friends can't play their instruments at all, and everyone but Kootie Pie can't stand the music. Bowser comes in to complain, but Toad's drumstick goes flying into his mouth, and he flees from the bad music, as do some Sledge Bros. and Goombas. Still playing, Mario and his friends lead Milli Vanilli out of the room, and head for the Warp Pipe. Kootie Pie, upset over the loss of her concert, runs to tell Bowser, and threatens to scream if he doesn't bring it back. Bowser, who is wearing earmuffs, refuses to do so, and would rather hear Kootie Pie scream than any more bad music. Kootie Pie claims that she'll just bring them back herself, but Bowser grabs her, and threatens to throw her in the dungeon (unless Kootie Pie promises to forget about the band), to which Kootie Pie gives up and promises to forget about them.
Back at their real concert, Milli Villi are back on stage, and announce that their next song is dedicated to a real princess, as they start to play "Girl You Know It's True". Watching from backstage, Princess Toadstool starts applauding, and ignores Mario, who comments that if they keep their band, they'll be as popular as Milli Vanilli, which he isn't too keen on.
