The Morning After the Fright Before
A Grave Situation
Batman, Gandalf, and Wyldstyle found themselves stumbling upon the Scooby-Doo! World, with Mystery Inc. going through the usual story plot: Fred started off with the splitting of the group for a more efficient search, he had Scooby-Doo and Shaggy ride the Mystery Machine to the fun-fair, while leaving him, Daphne, and Velma to search around his Uncle Arthur's Haunted House.
In order to find the Diamond Scarab, Batman, Wyldstyle & Gandalf then had to solve puzzles in the haunted house to find the foundation element, ultimately ended in a fight between the trio and the Mummy in the fun-fair tent.
With the Mummy defeated, they retrieve the Diamond Scarab and unmasked the perpetrator to be the fun-fair owner, but it's revealed to be Lord Vortech hidden beneath the disguise so that he could steal the final Foundation Element. The trio managed to escape with the help of X-PO as Vortech found out X-PO was the one helping them.
