Aloha Scooby-Doo! (2005)

The gang travels to Hawaii on a free trip from a surf-and-beachwear company called “Goha Aloha” thanks to Daphne, whom the company wants to design some new swimwear for them. The gang also goes there to see the Big Kahuna of Hanahuna Surfing Contest. However, the contest used to only be open for the natives and not for mainlanders, but now the mayor has made it open for everybody. Many locals are angry because of this, especially Manu Tuiama, a local surfer, and his friend, Little Jim. Just a few days before the contest, the demons of the evil Wiki-Tiki spirit attacked the village and kidnapped Manu’s girlfriend, Snookie. This drives away most of the tourists and surfers, and the locals believe the spirit is angry that the surfing contest is open to anybody, and also that a new resort, Coconut Beach Condominiums, is being built on supposedly sacred ground by local real estate agent Ruben Laluna.

When the gang meets Jared Moon, a representative from the Goha Aloha-company in Hanahuna, he’s selling tiki charms that are supposed to ward off evil demons. The mayor refuses to postpone the contest, even after the Tiki demons attack again at a feast. The gang wants to get to the bottom of the mystery, and go to Auntie Mahina, a local shaman who lives deep in the jungle. On the way there, Manu seemingly gets kidnapped by the Wiki-Tiki. Auntie Mahina tells them the Wiki-Tiki is angry at the mainlanders; the surfing contest is hinted by her to be a Hawaiian ritual and that the winner has to be of Hawaiian descent.
