Arrangements[edit]

Super Mario series[edit]

New Super Mario Bros. 2[edit]

In New Super Mario Bros. 2, a woodblock beat is added to the original "Underwater Theme" when Mario or Luigi are in their Raccoon/Fox forms, and a bell synth arpeggiator is added while the Gold Ring is active.

New Super Mario Bros. U[edit]

In New Super Mario Bros. U, vocalizations are added to the original "Underwater Theme" whenever a player holds onto a Baby Yoshi. This remix is reused for the same purpose in New Super Luigi U, New Super Mario Bros. U + New Super Luigi U, and New Super Mario Bros. U Deluxe.

Super Mario Maker[edit]

In Super Mario Maker, an ambient arrangement of the "Underwater Theme" using eight tracks that fade in and out randomly to create a dynamic mix plays while editing New Super Mario Bros. U-style underwater-themed courses in the Course Maker. Moreover, new percussion is added to the original "Underwater Theme" whenever Mario rides a Yoshi, as this was impossible in the original games. Both the arrangement and the remix are reused for the same purposes in Super Mario Maker for Nintendo 3DS and Super Mario Maker 2.
