This story is a sequel to G5 Adventures in Scooby-Doo! and Krypto Too

To get over the trauma of their last adventure, the Mane 6 follow Violette Rainbow to the Swirlpool Starlight, a magical event held once every 10 years. But as the Mane 6 get their future told, they get summoned on another adventure... hopefully less dangerous than the last.

Upon exiting the portal, they join forces with Scooby-Doo, Shaggy and the Mystery Inc. crew as they head to Chicago for a talent show, some museum tours and whole lotta pizza! The windy city is home to the hit TV show, Talent Star, in which songwriting duo Fred and Daphne are finalists with some high hopes. Not to be left out, Scooby and Shaggy have a secret act in the works, which they are betting will take the contest by storm.

Unlucky for them, the competition is frightful at this talent contest as the show is being broadcast from an opera house with a history of horrors and a particularly vengeful phantom that has cursed the show's production.

From costume changin' chases to collecting creepy clues, the Mane 6 and Mystery Inc team up with a trio of singing winged leopards to ensure that the show goes on, and with natural talents like the ponies and Scooby-Doo on the case, you can be sure that the laughs, thrills and adventure are always first place!
