"Records" is now renamed to "Mario U Records" and "Luigi U Records" in the American English version, depending on the game being played.
The Records Toad House pages now resemble a map marked with a red stamp depicting a silhouette of Nabbit's ears.
A neon Nintendo Switch console appears in the Records Toad House, which plays a music box arrangement of the game's credits theme while the Switch version's credits roll. On the pause screen, characters can be changed on the map screen. In the pause menu during levels, buttons on the controller can be remapped. In the red Toad Houses with ? Blocks, Toad gives the player all of the items inside the blocks that were hit, rather than just one. This is to prevent any accidental bubble activations if a player unintentionally presses a button. Two buttons are now used to go in the bubble in multiplayer by holding down the L and R rather than just one button, unlike the original game. However, this has to be done each time the game starts up. When Nabbit's voice is heard, the jump controls have been disabled for the mid-air spin. The mid-air spin can be disabled by holding the left stick down for three seconds on the title screen while pressing the L and R buttons simultaneously.
The jump controls are now shared with the mid-air spin, performed by pressing B or A in mid-air, consistent to a similar control scheme in Super Mario Run, having the techniques mapped to a touch input. U, a red-colored Super Guide Block appears (if players lose multiple lives in a level) and summons a computer-controlled Mario to clear the level, replacing Luigi. U and the New Super Luigi U levels start with 100 additional seconds on the timer when playing as either Toadette or Nabbit, though no bigger time bonus is given when both of them are being played. Playing as a Mii is no longer possible in Flying Squirrel Ovation within New Super Luigi U. Because of this, Toadette replaces Blue Toad in the game's cutscenes. Yellow Toad and Blue Toad share the same character slot and are referred to as "Toad". The option menu before the character selection screen where the player decides whether to play with the Wii U GamePad or multiplayer with the Wii Remote or the Wii U Pro Controller has been removed since the Joy-Con has the capability to switch between modes.
