Crystal Palace

The Crystal Palace is where the last Star Spirit is being held in Paper Mario. This palace is a 'mirror' filled castle with puzzles in every which way. Mario and his teammates must solve the puzzles and fight off many Duplighosts and White Clubbas to get to the boss. After solving the puzzles, they manage to reach the boss: the Crystal King. After they defeat him, they free the last Star Spirit, Kalmar.
