Twink is a Star Kid (a star shaped child) which deliver messages to the Star Spirits. He is also a major character in Paper Mario.

Twink first appears at the end of the prologue where he attempts to help Princess Peach, unfortunately he is not strong enough to help her escape. Twink is still helpful, acting as a messenger between Mario and the princess, delivering information on the location of Star Spirits and other useful information. Eventually when Bowser planned on imprisoning the princess on his newly built battlefield Twink attempts to stop him, unfortunately Bowser simply swats Twink out a nearby window.

Twink reappears near the end of the game, here the player takes direct control of Twink to battle Kammy Koopa. At first capable of only minimal damage, Twink gradually grows stronger with help from Princess Peach, whose wishes empower him. Defeating Kammy, Twink manages to distract Bowser long enough for the Star Spirits to give Mario the "Peach Beam", an attack that can counter Bowser's battlefield and the Star Rods power.

When Bowser is defeated Twink, for his bravery, is given the honor of becoming a full fledged star.

Twink makes a small appearance in the victory parade at the end of the game, briefly seen on Mario and Peach's float.
