List of sound effects in Super Mario Maker 2

Sound effects return from Super Mario Maker in Super Mario Maker 2, with new additions. All of them are now categorized in five different groups similar to the course elements: feelings, stingers, reactions, animations, and music. When playing in an underwater or Ghost House course set at nighttime, certain sound effects serve as temporary light sources when they are triggered.

Super Mario Maker 2 features a total of 47 sound effects. Sound effects in bold are new. The rightmost column describes what each sound effect does when dragged and dropped onto the player character in the course editor. Unlike power-ups, the sound effect dragged and dropped onto the player character is saved to the course, and will be present when it is played outside of the course editor.

Feelings
The feelings category is represented by a yellow smiling face.

Stingers
The stingers category is represented by a "!?" and colored red.

Reactions
The reactions category is represented by split arrows and colored green.

Animations
The animations category is represented by sparkles and colored purple.

Music
The music category is represented by a blue vinyl record. Placing any of these sound effects onto the player in the editor will cause the song to play throughout the entire course (including subarea) unless overridden by another sound effect. If placed on an enemy, the music will play as long as the enemy is on screen. Music will override each other with priority depending on what the music is placed on. Priority goes as follows: On Mario < On background < Triggered from block < On enemy (closest enemy takes priority) < On a moving lift
