This story is a sequel to G5 Adventures in The SpongeBob Squarepants Movie
With one crystal found, the ponies know that whatever dark force the crystals were made to protect Equestria from must be drawing closer. But before they can ask more questions, they are drug away on another Unity Quest... this time to Nowhere, Kansas.
Comedy is unleashed when Scooby-Doo and our pony pals team up for the first time with Courage the Cowardly Dog, where the dogs sniff out a mysterious object beneath Nowhere that seems to make some super strange things happen.
Soon, the mysterious discovery puts them on the trail of a giant cicada monster and her wacky winged warriors, and the gang knows they'll need more than a flyswatter to solve this case. Can Scooby, our pony pals and Courage overcome their jitters and defeat the insect army before the whole world bugs out? And will Misty be able to confront a mysterious figure from her past who seems to be working for the wrong side?
Try not to get scared. We double-dog dare you!
