Plot
Mystery Inc. receive a free trip to Hawaii from a surf-and-beachwear company called "Goha Aloha", who wants Daphne Blake to design new swimwear for them. Upon their arrival, the gang meet with Jared Moon, a representative of Goha Aloha and learn of the Big Kahuna of Hanahuna surfing contest, which was originally exclusive to native islanders before the mayor opened it to mainlanders over several islanders' protests, such as local surfer Manu Tuiama and his best friend, Little Jim. The former is especially upset over this because he claims that the ancient Wiki-Tiki spirit sent demons to attack his village and kidnap his girlfriend Snookie in retaliation for the mayor's actions and because local real estate agent Ruben Laluna built a residential complex on sacred ground.

While investigating the attacks, the gang and Manu visit Auntie Mahina, a local shaman who lives deep in the jungle, but Manu is seemingly kidnapped by the Wiki-Tiki along the way. Mahina tells the gang that the Wiki-Tiki is angry because the surfing contest is a Hawaiian ritual and that the winner must be of Hawaiian descent before telling them to head to a nearby volcano or else Manu and Snookie will be sacrificed to the monster. Before they leave, Mahina gives Fred Jones a necklace containing bola gawana root extract, which she says will ward off the Wiki-Tiki. Eventually reaching the volcano, the gang find Snookie, but she is recaptured by the Wiki-Tiki, who proves immune to the necklace.

After making their escape, the gang discover the Wiki-Tiki's demons are remote-controlled robots and a picture of the Wiki-Tiki itself using a Goha Aloha brand surfboard. The next day, Daphne enters the surfing contest to lure out the monster. With Shaggy and Scooby's help, she eventually defeats it, allowing the others to unmask it as Manu, who they reveal worked with Snookie to scare off locals and tourists so they can buy their homes and sell them back at higher prices. Additionally, Snookie is a rocket science and robotics expert who created and operated the robots to further their scheme. As the criminals are arrested, Scooby is named the new Big Kahuna of Hanahuna for his work in stopping Manu before the gang celebrate at a luau.
