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 up to two minigames the enemy characters have appeared in as well as playing them from the Character Museum.
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.
