Rolling Down the River

Rolling Down the River is the fifth episode of The Super Mario Bros. Super Show!. Its corresponding live-action segment is "The Mario Monster Mash".

Plot Synopsis
Princess Toadstool has been captured by Captain Koopa, who is now racing down the river of the River World in his ship, the Sinister Star. As Captain Koopa paces back and forth near the steering wheel of the Sinister Star, First Mate Mouser appears from below deck to report that he has found no trace of any stowaways. Not satisfied with this, Captain Koopa violently shoves First Mate Mouser aside and ventures below the deck of the Sinister Star.

Down below decks, Mario and Luigi, wearing trench coats, are in the middle of a game of Go Fish against two Koopa Troopas and a Goomba. Winning the game, Mario proceeds to grab and count the large pile of coins he won. As Mario continues to count his coins, Luigi whispers to him, asking how much longer they need to distract the Koopa Troopas and the Goomba; Mario whispers back that they need to keep them distracted until Toad finds and releases Princess Toadstool.

Up above, on another floor of the Sinister Star, Toad, carrying a silver platter and disguised as a waiter, approaches a locked door. Toad proceeds to tell the door's Goomba guard that he is here to deliver a birthday cake to the captive Princess Toadstool and proceeds to show the Goomba a rather poorly made cake. Suddenly, Toad is grabbed from behind by Captain Koopa and drops his cake on the ground, revealing various instruments of escape hidden in it, which includes a file, a hacksaw and two hand drills. Opening Princess Toadstool's cell door, Captain Koopa throws Toad into the cell near Princess Toadstool and proceeds to tell the Goomba guard to be on the watch for Mario and Luigi.

Above deck, Mario has just won another game of cards, while Luigi is begins to worry about Toad. Calming Luigi down, Mario notices a Goomba hop by with a plate of chicken on its head; running up to the Goomba, Mario grabs a piece of chicken off its plate and takes a bite of it, though in the process, lets several cards fall out of his coat sleeve. A Koopa Troopa, seeing the fallen cards, approaches Mario and accuses him of cheating and struggles to pull his coat off, revealing several more hidden cards. Managing to pull Mario's coat off, the Koopa Troopa realizes it was Mario he was playing against the entire time; as Mario and Luigi begin to run away, the Koopa Troopa, the other Koopa Troopa and the Goomba give chase to them.

Chased to the upper levels of the Sinister Star, Luigi sheds his disguise as the Koopa Troopas and Goomba continue to chase him and Mario. Chased to the highest level of the Sinister Star, Mario and Luigi see no other alternative than to jump overboard into the river to escape the pursuing Koopa Troopas and Goomba.

In the river, Mario and Luigi are suddenly attacked and chased by a knife and fork wielding Trouter. Trying to escape the Trouter, Mario and Luigi suddenly get caught in a lasso and are dragged aboard a ship; once on the ship, Mario and Luigi meet Mark Twang, the captain of the Ding Bell.

Befriending Mark Twang, Mario and Luigi tell him of Princess Toadstool's capture by Captain Koopa and also learn that Mark Twang is after the Sinister Star as well; it seems Mark Twang had entered a race against Captain Koopa, with whoever winning the race becoming the King of the River. Unfortunately, it seems Captain Koopa had sabotaged the engine of the Ding Bell, wrecking it almost completely. Deciding to help Mark Twang, Mario and Luigi decide to repair the Ding Bell's engine.

Onboard the Sinister Star, Captain Koopa is in the process of taunting Princess Toadstool and Toad while First Mate Mouser keeps lookout with a telescope. Seeing the Ding Bell, First Mate Mouser proceeds to alert Captain Koopa of this. Grabbing the telescope from First Mate Mouser, Captain Koopa, wondering how Mark Twang fixed his engine, sees Mario and Luigi riding the Ding Bell; Captain Koopa, furious, throws his telescope to the ground and stomps on it.

Steering the Ding Bell, Mark Twang informs Mario that they need more speed to catch-up to Captain Koopa and the Sinister Star; through an intercom, Mario manages to tell Luigi, who is in the Ding Bell's engine room, to increase their speed. Onboard the Sinister Star, Captain Koopa, wanting to get rid of the Ding Bell, orders First Mate Mouser to bring him a Black Pit Bob-omb; hesitantly, First Mate Mouser brings forth a chest containing an enormous Bob-omb and passes the explosive to Captain Koopa. Lighting the fuse of the Black Pit Bob-omb, Captain Koopa hurls it into the river near the Ding Bell, where it creates a monstrous explosion which in turn, creates a large, gaping, black pit.

Seeing the black pit, Mark Twang begins trying to steer the Ding Bell away from it, only to be sucked closer to it by the current of the water. As Mark Twang begins to lose hope of escaping the black pit's pull on the Ding Bell, Mario and Luigi begin to enact a plan; taking out his plunger, Mario ties some rope to the end of it while Luigi wheels a cannon near him. Loading his roped plunger into the cannon, Mario fires it at a nearby, target engraved rock; the plunger attaches to the rock, anchoring the Ding Bell in place. As Princess Toadstool and Toad cheer for Mario, Captain Koopa begins to taunt them, saying that there is no way the Ding Bell will ever pass the black pit.

Having docked the Ding Bell near the target emblazoned rock, Mark Twang proceeds to tell Mario and Luigi that they should see the Mouth of the River, a woman who knows everything about River World and who may be able to help them pass the black pit. In a parked caravan, Mario, Luigi and Mark Twang find the Mouth of the River and ask her how they can get the Ding Bell passed the black pit; the Mouth of the River proceeds to give Mario, Luigi and Mark Twang some cryptic advice, saying have the river "go around" the black pit.

Near where the Ding Bell is docked, Mario and Luigi are just finishing what appears to be a large, intricate piping system. Turning the piping system on, Mario, Luigi and Mark Twang watch as a pipe sucks up the water of the river and places it in a passage separated from the black pit by a wall of rocks. With this newly created, miniature river, having the Ding Bell pass the black pit is easy.

Despite passing the black pit, Mark Twang still believes he will not be able to catch-up to Captain Koopa and the Sinister Star, which is extremely far ahead. The Mouth of the River, who has joined the crew of the Ding Bell, says that all hope isn't lost and proceeds to give Mario and Luigi a pair of magic pendants, saying they'll help Mario and Luigi. Putting the pendants on, Mario and Luigi are transformed into Super Mario and Super Luigi.

Aboard the top deck of the Sinister Star, Captain Koopa and a rather bored looking First Mate Mouser are on the look-out. Seeing the Ding Bell approaching, Captain Koopa, in his frustration, throws his telescope at First Mate Mouser and proceeds to stomp on it again when it lands on the ground. Onboard the Ding Bell, Mario and Luigi, with their new super-strength, are jumping up and down on a pump-like mechanism, pushing the Ding Bell forward as the Mouth of the River cheers them on.

Pulling-up alongside the Sinister Star, Mario and Luigi leap from the Ding Bell and land on the Sinister Star as the Ding Bell speeds ahead. As Princess Toadstool, Toad, First Mate Mouser and several Koopa Troopas watch, Mario and Luigi effortlessly lift Captain Koopa above their heads. As Toad and Princess Toadstool thank Mario and Luigi for rescuing them, Captain Koopa suddenly grabs the empowering pendants from around Mario and Luigi's necks; without the pendants, Mario and Luigi lose their superpowers and regress to normal and are easily subdued by Captain Koopa.

Afterwards, Mario is being forced to walk the plank of the Sinister Star by Captain Koopa, First Mate Mouser and a Koopa Troopa. As Mario prepares to be shoved into the river, where several hungry Trouters await, the Ding Bell appears and begins to blast the Sinister Star with Turnips, fired by the Mouth of the River and a cannon. As Captain Koopa orders First Mate Mouser and a Koopa Troopa to return fire on the Ding Bell, the driver of the Sinister Star, Clawgrip, is knocked aside by Turnip projectile; with Clawgrip knocked unconscious, Princess Toadstool manages to take hold of the Sinister Star and begins to steer it towards a nearby beach.

Charging towards the beach at full speed, Princess Toadstool has the Sinister Star crash into it with enough force to send Captain Koopa flying off the ship. Sent spiraling through the air, Captain Koopa plummets towards the sand and lands in it, becoming buried and left vowing vengeance on the laughing Mario, Luigi, Toad and Princess Toadstool.

As the Ding Bell reaches the finish line of the river, Mario, Luigi, Toad and Princess Toadstool congratulate Mark Twang on becoming King of the River. After congratulations are done, Mario, Luigi, Toad, Princess Toadstool and Mark Twang await their victory lunch, which was made and is being served by the Mouth of the River. As the Mouth of the River gives Mario his lunch, she tells him its catfish pizza, which Mario is hesitant to try, as the catfish on the pizza is still raw and uncooked.

Animation and Continuity errors

 * The mustache Toad wears as a part of his sailor disguise continues to disappear and reappear throughout the episode. Additionally, the target emblazoned on the rock where the Ding Bell is docked continually appears and disappears.
 * When Captain Koopa is being held in the air by Mario and Luigi, First Mate Mouser and a Koopa Troopa can be seen in the background; yet, when Captain Koopa is dropped by the de-powered Mario and Luigi, First Mate Mouser and the Koopa Troopa are simply gone.

Trivia

 * Coincidentally (or not) the song Proud Mary, which was covered in the episode, has the line "Rolling on the River", which is simiar to the title of the episode.
 * When this was being reran on Family and USA as a part of "Mario All-Stars", the scene where the Marios and Mark Twang visit the "Mouth of the River" was cut.
