Lucky Star (Paper Mario)

The Lucky Star is a special item in Paper Mario. It is a pendant belonging to Princess Peach, given by Twink to Mario early in the events of the game. The pendant gives Mario the ability to execute the Action Command for added attack and defense power. After Peach summons Twink while in captivity, she gives him the pendant, requesting he deliver it to Mario and inform him of her well-being.

Just after Mario speaks with the Star Spirits on Shooting Star Summit, Twink drops down to introduce himself, informing him that the princess is in good condition and is counting on him to save the Mushroom Kingdom before handing over the Lucky Star. Right after this, Mario battles a Magikoopa, giving him the opportunity to test out the new Action Commands given to him by the pendant.

In volume 26 of Super Mario-Kun, though the Lucky Star appears later in the story, it is received in a similar method - Twink receives the Lucky Star from Princess Peach before delivering it to Mario. Once Mario has the Lucky Star, he is able to plow through a Magikoopa.
