"The tarantella plays as legendary Luau Brothers Pablo, Tyrone, and Austin try to appease Volcano Sisters Tasha and Uniqua so their volcano doesn't erupt and ruin the big luau!"
Pablo, Tyrone, and Austin are in the backyard. They introduce themselves as the legendary Luau Brothers, a group of siblings living in Hawaii that can do extraordinary things. Tyrone proves to the viewer that he can lift heavy items by picking up a lawn chair, and he explains that he is called Tyrone the Strong. Pablo runs around in circles very fast, causing him to be called Pablo the Swift. Austin stands near the porch of Tyrone's house doing nothing. Pablo and Tyrone tell the viewer that he is called Austin, just Austin. The three sing "We Love a Luau" and also tell that they are heading to Hawaii for a big luau.
The backyard transforms into Hawaii. Two brown beach huts are shown. Pablo, Tyrone, and Austin appear. They are about to start their luau when they hear a yell from inside a volcano behind them. At the sound of the yell, they dash inside the high volcano full of lava. Inside the volcano, two sisters, Uniqua and Tasha, are sitting on a pedestal next to a red button. The girls tell the boys that they are mad, and if they do not get what they want, they will push the button, and the volcano will erupt. The Luau Brothers sing "We'll Get You What You Want" with the Volcano Sisters and leave.
Pablo and Tyrone try to decide what to give the sisters, but leave Austin out, who is trying to tell them what he thinks they will enjoy. Tyrone tells Pablo that the Volcano Sisters will want something large, and that he could fetch the Very Heavy Tiki Mask on top of Tiki Mountain and bring it to the sisters. Pablo agrees to the idea. Austin, feeling left out, follows the others to Tiki Mountain. At the mountain, Tyrone begins to climb up. There are many rocks covering the landform. His foot pushes a pebble off the mountain, causing rocks and boulders to roll down the mountain. Tyrone flings and dodges them all the way up. He reaches the mask.
Tyrone carries the mask down the mountain and signals for the other Luau Brothers to come with him to the volcano. They do so. At the volcano, Pablo and Austin introduce Tyrone with the mask. He brings it forward. After looking at the mask, Tasha pulls a lever, causing the mask to bounce back on top of Tiki Mountain from inside the volcano. They yell, "That was not what we wanted!" Tyrone is disappointed. Uniqua and Tasha yell "Now go!", causing the Luau Brothers to bounce out of the volcano. Pablo decides to journey deep into the ocean to swipe the World's Shiniest Pearl from a giant clam that he has heard of. Tyrone agrees to the idea. Austin tries to protest, but is once again left out.
Pablo brings Tyrone and Austin to the edge of Hawaii. He plunges into the ocean and finds a large gray clam sleeping. Beside the clam, there is a white pearl. He silently takes the pearl, causing the giant clam to wake up. The clam chases Pablo for the pearl back, but Pablo escapes. He brings the pearl to the volcano where Uniqua and Tasha wait. At the volcano, Uniqua and Tasha study the pearl, but Uniqua pulls a lever, causing the pearl to bounce back into the ocean where the giant clam rests. They yell, "That was not what we wanted!" Pablo is disappointed. The brothers return to the beach.
The cast sings "Huka Pele". On the beach, Pablo and Tyrone express their frustrations about their presents rejected by the sisters and give up. Finally fed up with his brothers ignoring him, Austin shouts and finally gets their attention. He tells Pablo and Tyrone that he has been trying to tell them that he has a great idea. He walks over to a small patch of flowers. He pick one pink and one yellow flower. Pablo and Tyrone are petrified at the thought of Uniqua and Tasha disliking the other presents and receiving Austin's. Austin brings the others to the volcano where he politely hands Uniqua and Tasha their flowers and invites them to the brothers' luau, which made Pablo and Tyrone surprised and confused. Uniqua and Tasha are now happy and thank Austin. It was exactly what they wanted: go to the luau. They head out of the volcano.
Outside, the luau starts. The five characters sing "We're Glad" after the Volcano Sisters reward Austin and rename him Austin the Smart. Pablo and Tyrone apologize to Austin for not listening to him from the start. Tasha's stomach growls. Tyrone asks if the sound was a volcano eruption. Tasha tells him that it was just her stomach and Pablo invites the others over for orange slices at his house. The cast sings the end song and heads to Pablo's house for a snack. Austin opens the previously closed door and exclaims, "Aloha! That means goodbye, too."
