"Do the Koopa" is the fifteenth episode of The Adventures of Super Mario Bros. 3; it aired alongside another episode of The Adventures of Super Mario Bros. 3 entitled "Kootie Pie Rocks." The title of the episode is a play off "Do the Mario", the song that is used in the closing credits to The Super Mario Bros. Super Show!, the previous Mario animated series produced by DIC Entertainment.

Plot synopsis[edit]

The episode begins with Luigi finding a treasure map to the Doom Dancer Music Box in Mushroomland Central Library. 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 Kastle 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.

Mario and Co. face a problem getting over a wide gap. Toad suggests that Mario break some blocks to get some Super Leaves, which Mario does. Turning into their Raccoon forms, the group flies over the wide gap. They run through a field of giant spikes popping down from the cave ceiling. After getting through the spike field, two Koopa statues turn them all back into their normal forms.

The Temple of Gloom.

After traversing through a hallway, the group sees the Temple of Gloom, which is guarded by a group of Dry Bones. The group stomps on all the Dry Bones, but they just reform and get back up. Mario then sees a group of Blocks and tells everyone to break them. The rubble of the blocks block the Dry Bones from reaching the gang, allowing Mario and the group to get into the Temple of Gloom safely.

Cheatsy, Bully, and Big Mouth are later seen clearing the rubble, and following the gang into the Temple of Gloom. After narrowly avoiding beams from many Koopa statues, Mario and the gang reach a door. Princess Toadstool looks at the map and tells the group that the Doom Dancer is in the Inner Temple. The Koopalings, who are eavesdropping, realize that the Doom Dancer exists and is not a myth like their father always thought. The Koopalings decide to let Mario get the Doom Dancer, then Big Mouth says they should ambush them. Bully tells Big Mouth to give him his string. Big Mouth objects because it belonged to their great grandmother and attempts to tell an unneeded story about her. Bully covers his big mouth before he starts while Cheatsy steals the string and creates a trip-wire.

Traps going off after Mario grabs the Doom Dancer.

Mario and the group are then seen inside the room of the Doom Dancer, which is on a pedestal. Mario climbs up and obtains the Doom Dancer, which sets off a trap that makes projectiles fall from the ceiling. Mario gets back to the group after narrowly avoiding a Thwomp. A Boom Boom scares the group and sends them running outside, tripping on the trip-wire and sending the Doom Dancer into the air. Big Mouth attempts to catch it while mimicking football game crowds, but Cheatsy pushes him aside and attempts to catch it, but Bully grabs him by the hair and throws him away and the Doom Dancer falls into Bully Koopa's claws. Bully then uses the Doom Dancer to force everyone to dance, even his own siblings. He makes everyone march back to Castle Koopa, plotting to use the Doom Dancer to overthrow his father.

Bully with the Doom Dancer.

When the group gets to Kastle Koopa, King Koopa asks Bully to give him the Doom Dancer. Bully refuses, saying that he is going to use it to rule the entire world, starting with his father. However, King Koopa's cold prevents him from hearing the music, making him invulnerable to its magic. Koopa then takes the Doom Dancer, and cranks it, making everyone "Do the Koopa". King Koopa then says that he is going to make the whole Mushroom Kingdom dance to their doom. The Doom Dancer is powerful enough for its power to spread into Desert Land where a Sphinx, the trees and even the enemies start dancing.

King Koopa then flies over various parts of the Mushroom Kingdom on his Doom Ship, making everyone "Do the Koopa", even statues and plants. Mario then gets some Plumber's Putty from Luigi, and jams them in his ears, blocking out all sound. Pretending to dance, Mario slowly goes towards Koopa, tackling him and sending the Doom Dancer into the air. A struggle for the Doom Dancer follows, which ends up in the crank breaking off from the rest of the Doom Dancer. Attempting to crank it with his claw, Koopa gets his claw stuck. The Koopalings help Koopa get it off, but send the Doom Dancer crashing onto the landscape below, where it hits a Goomba on the head and breaks.

King Koopa, Bully, and Cheatsy then start arguing over whose fault it is for breaking the Doom Dancer. Mario and the group jump into the Warp Pipe and get warped to Mushroom Castle, where the episode ends.
