Paper Mario: Summer Crystal is the 6th installment to the Paper Mario series, following the events of Paper Mario: Color Splash. This game is in the action-adventure and role-playing genre. Unlike its last three games, Paper Mario: Summer Crystal uses the original battle system, like Paper Mario: The Thousand Year Door.
The story focuses on Mario and Peach vacationing to a tropical getaway island called Ultraviolet Island. The main goal of the game is to collect the seven shards of the Summer Crystal, the main power source of Ultraviolet Island. The island terror, Summer Phantom, wants the Summer Crystal for himself, so he can take the power and rule the Mushroom Kingdom. Meanwhile, Daisy gives Luigi his own quest to save Princess Eclair from the sinister Crepe.
Prologue: Summer Getaway Gone Wrong Mario and Luigi are invited to an auction that Peach and Daisy are hosting at Mushroom Castle, and after all the items are sold, Peach invites Mario on a trip to Ultraviolet Island. Mario later learns that the island has a secret dark side, and someone is after one of Ultraviolet Island's prized possessions. A flower shop owner named Goombianca helps Mario out and joins him on his quest.
