Pearl, Diamond and Lady Berlitz finally reach the base of Mt. Coronet. They're all set to scale its cloudy peak...but first, there are dancing contests to win, badges to compete for and enemies to evade! Speaking of enemies, are those shadowy figures members of...Team Galactic?! Plus, meet Roserade, Stunky, Probopass, Buneary, Pachirisu, Croagunk, and many more Sinnoh Pokemon friends!

Three kids are given the challenge of a lifetime; to be let loose in the world's greatest museum after hours to unlock the mystery behind famous artifacts. It's not going to be easy and they must race through the museum and complete complex challenges and confront visions from the past in their quest for answers. What's more the halls are patrolled by evil spirits and security guards who must be avoided at all costs.
