Happy Halloween, Scooby-Doo!

Mystery Inc. withdraws from solving crimes after botching a case. When Vincent Van Ghoul contacts the gang about an unfinished investigation from Daphne, Shaggy and Scooby's past, the gang springs into action to finish the job that involves catching the 13th Ghost that escaped from the Chest of Demons and is still at large.

Scooby-Doo and the Mystery Inc. gang meet up with Batman and other friends to defeat evil villains and save the day.

Halloween is almost here and George can't wait for the festivities to begin: carving pumpkins, costume contests, and especially the Annual Boo Festival. Eager to get the festivities started, George and Allie visit Renkins' Farm to pick out the perfect pumpkin. There, they are told the spooky tale of the Legend of No Noggin. As the story goes, No Noggin is a hat-kicking scarecrow who appears on Halloween to kick people's hats off. On Halloween night, George and Allie are determined to get a picture of No Noggin and prove he's real once and for all. Will they be able to get the proof? Only the curious will find out!

Unjustly accused of staging a spooky practical joke complete with ghosts, Daphne, Velma, Fred and Shaggy are suspended from Coolsville High. To clear their names, they team up to solve the supernatural mystery…and head straight into nonstop laughs and adventure.
