Mary O.

Mary O (middle) riding on a cloud.

Mary O is the helpful guide in Super Mario Maker. She is available to be spoken to at any time from the game's menu, by tapping the green manual icon. Her role is to assist the player, and share information about the game's content. Her appearance is that of a young female with blue eyes and dark hair, and a headset on. Her name purposely is meant to sound like Mario's name.
