Twink is the star kid who helps Peach during the castle segments of Paper Mario.
While Mario travels through the Mushroom Kingdom, Princess Peach remains trapped in her castle, which Bowser has lifted into the sky. Between Mario’s chapters, players control Peach as she explores the castle and looks for ways to help the rescue effort.
Twink, a young Star Kid, becomes Peach’s ally during these sequences. He helps her gather information and carry messages or useful clues to Mario. His role connects Peach’s quieter investigation scenes with Mario’s active journey to rescue the seven Star Spirits.
Twink is easy to confuse with later Paper Mario helpers. Olivia is the origami companion in The Origami King, Huey assists Mario in Color Splash, and Kersti accompanies him in Sticker Star. None of those characters appears in the original Paper Mario; Twink is specifically its Peach-side companion.
