It's the big kahuna of Scooby-Doo movies!
Shaggy, Scooby-Doo and the Mystery Inc. gang hit the bodacious beaches of Hawaii for the Big Kahuna of Hanahuna Surfing Contest - only to discover there's a terribly real monster about to show all the true meaning of wipeout! The locals are convinced that island spirits are furious over a new resort being built on sacred ground and when an army of tiny demons attacks the surfers, the ancient prophecies appear to be true. Could this be the first mystery that Daphne finally can't figure out before trouble - in the form of a huge volcano - erupts? Grab your surfboards and hold onto your coconuts - unless Scooby-Doo and Shaggy don't munch'em down first - for a spectacularly colorful and splashy animated adventure.
