Aloha, Scooby-Doo!

Surf's up! Daphne is working with a clothing designer in Hawaii, and the kids from Mystery, Inc. are ready to say aloha to a free trip to the islands. They're looking forward to sun, sand, and surf. And they're stoked to find out that the Big Kahuna Surfing Contest will take place while they're visiting. But before the kids have a chance to hang ten, the beach is invaded by an evil Wikki Tiki monster. He's freaked that mainlanders are competing in the contest, and he'll do anything to stop them. Can the gang catch the Wikki Tiki before it's too late? Or will this case be a wipeout?
