IT's FINALLY HAPPENING. フレッド and Daphne are getting married and in less than a month, the wedding will happen. Of course Velma will be Daphne's Maid of Honor and Shaggy being Fred's Best Man. As for Scooby-Doo, he is the Best Dog. Old フレンズ will reunite for this special occasion. However, just as this will be a event of a lifetime...there is always a monster waiting. When Daphne receives a rare blue amulet, she and the Mystrey Inc. gang has no idea the amulet will awaken the vile Shadow Creature. And if that's not bad enough, the couple are getting cold feet before the day. With a creature on the loose, family and フレンズ unaware they are in danger, and the couple nervous, Shaggy and Scooby will try their best to make things calm, yet can't wait to get to the buffet at the reception--if only they can make it there.
