Peach's Crown

Princess Peach's Crown is Princess Peach's emblem and a symbol of the Mushroom Kingdom. The only significant role it has played is being a lost object that must be retrieved.

In the Nintendo Comics System issue Cloud Burst, Princess Peach has lost her crown and needs it for her yearly recoronation, so she sends Mario and Luigi to retrieve it. She believes King Koopa to have stolen it as he is invading "World 3". In reality, it was stolen, along with King Koopa's crown, by a Lakitu and the plumbers eventually get it back for her.

In Super Mario RPG: Legend of the Seven Stars, Princess Peach loses her crown during her wedding to Booster and Mario has to find it. Mario eventually finds the crown on top of Booster's head. Depending on how fast Mario finds this and a bunch of Princess Peach's other items, he may receive a kiss from Peach (if he does it very slowly, Booster, Bowser, or even both may kiss him).

In Mario & Luigi: Partners in Time, Peach's crown can be found on the top of the Thwomp Volcano.

Trivia

 * A treasure in Pikmin 2 strongly resembles Princess Peach's crown.
 * In Paper Mario, Princess Peach's crown never falls out of her head, even when she's thrown onto the ground by the Koopatrols.
