Slider

"Slider" is a musical theme composed for Super Mario 64 by Koji Kondo. It is a frantic country/ska interpretation of the "Super Mario 64 Main Theme" motif, played in D major at a presto tempo.

Super Mario 64
In Super Mario 64 and Super Mario 64 DS, "Slider" is the background music in Rainbow Ride, Tick Tock Clock, and all Secret Slide areas, and during Koopa the Quick's footraces. The melody is played on harmonica, and the countermelody on whistle, with banjo, acoustic bass, and drumset as accompaniment.

The original "Slider" returns in Super Smash Bros. for Wii U as one of the selectable songs for the Peach's Castle stage, and in Super Smash Bros. Ultimate for any Mario-series stage, both games in which they are named "Slide".

"Slider" is also reused in Super Mario Maker 2 as a sound effect in the music category, represented by the Nintendo 64 logo. It has a new fast version for when the Time Limit decreases below 100 seconds.

Super Mario Galaxy 2
In Super Mario Galaxy 2, an arrangement of "Slider" is used for the slide in Tall Trunk Galaxy, and while rolling the Star Ball or Purple Coin Ball in Rolling Coaster Galaxy. In the latter case, it adjusts in tempo and intensity to match the speed of the ball, fading into a sparse version played on sine synthesizer, two recorders, and harp if it is kept still, and increasing in speed (affecting the pitch continuously, as opposed to an increase in tempo) when the ball accelerates down the rail launchers.

Super Mario 3D World
In Super Mario 3D World, an arrangement (titled "Plessie's Plunging Falls" in the official soundtrack) is played while riding Plessie. The accompaniment uses guitar and bongos.

Super Smash Bros. Melee
In Super Smash Bros. Melee, an orchestral arrangement of "Slider" was arranged for the Rainbow Cruise stage by HAL Laboratory composer Shogo Sakai, under the same name as the stage. The arrangement also incorporates the Underwater Theme from Super Mario Bros.

The song returns for the same stage in Super Smash Bros. Brawl (titled "Rainbow Cruise (Melee)"), for Smash Run in Super Smash Bros. for Nintendo 3DS, for the Delfino Plaza stage in Super Smash Bros. for Wii U, and for every Mario-series stage in Super Smash Bros. Ultimate (titled "Slide").

Paper Mario: Sticker Star
In Paper Mario: Sticker Star, a big band arrangement titled "Go Go Trolley!" ("Go, Go, Trolley!" in the British English version) is played during the mine cart ride in Bowser's Snow Fort.

Mario & Sonic at the Sochi 2014 Olympic Winter Games
Another big band arrangement was created for Mario & Sonic at the Sochi 2014 Olympic Winter Games. The arrangement opens with an original introduction played on trumpet and electric guitar, the former of which is used for the main melody for the remainder of the song, and trumpet, saxophone, and electric guitar solos are added partway through the song.

Mario & Sonic at the Rio 2016 Olympic Games
A different arrangement was created for Mario & Sonic at the Rio 2016 Olympic Games, though this version is more faithful to the original "Slider" than its predecessor's.

Captain Toad: Treasure Tracker
In Captain Toad: Treasure Tracker, an arrangement of "Slider" is played in the Coins Galore levels.
