Character Museum

The Character Museum is a mode in Mario Party: Star Rush that allows players to view characters and bios. Players can view characters by changing the camera angle of the character as well as activating various animations for characters such as winning and losing animations; most characters have more than one animation that can be viewed. The Staff Credits can also be viewed in the Character Museum once the Staff Credits are unlocked by reaching Level Star. In addition, players can view which minigames the enemy characters have appeared in as well as playing them from the Character Museum. Despite this, some minigame entries for characters are omitted, such as Rolling Rumble featuring Koopa Troopas, even though Rolling Rumble is not listed in the minigame appearances and Bowser does not have any minigame appearances, even though he appears in six minigames.

If players have amiibo, players can tap them in to unlock stamps related to the character on the amiibo. The stamps are based on the character's respective emblems and the quality of the stamp is dependent on how long the players hold the touch screen. Whenever players unlock stamps, they earn points to increase their Party Level.
