The kids at Sky High are enjoying a day at the beach in Dolphin City. Layla, Zach, Mesprit, and Magenta were relaxing, Will, Uxie, Warren, and Azelf were playing volleyball, the ponies were collecting shells, Stitch, Angel, Sparky, Felix, and The Pokemon Pets were dancing to Sample's music, CLST was splashing in the water and Lilo was surfing. There she came in while CLST came out rooting for her. Then the ponies came in with the shells they collected, "The Little Mermaid would've loved these." Sunny said in her mermaid-like swimsuit.
There they saw Mystery Inc Vampire, they were there for the Vampire Rock Musical Festival. In fact, that's where the Sky High Australian Trip Program is going to learn about outdoor survival. Fred thought that they would join them for the fun of camping. They accepted it, as long as Shaggy and Scooby don't hog all the food. "Do you think Snow White should enter?" Sunny asked.
During the ride, Teal was playing a video game, "Hoss Delgado: Vampire Crusher" when he saw a pirate-themed band leaving Vampire Rock. He got confused on what's going on. "Game over for that pirate crew," Teal said to himself.
During the trip, Mr. Boy taught him about the nature of The Australian Outback, Coach Boomer taught them how to fish with a net, and during the evening, Mr. Medulla taught them how to make a fire normally. Tori, Layla, Sunny, The Ponies, Mesprit Twinkle, and Phoebe were having some Quandongs, Bush Yams, and Bush Bananas while everyone had seafood.
"Yummy food." Stitch said.
Later when they were at the campfire, Mr. Boy was telling them about the legendary yowie. Will saw Tori leave the campsite. There he and Uxie followed her to a rock where she can see a full moon. Will thought they can try some dancing. There they danced to the hit song, "Dancing on The Moon" only to fuse into a giant blue 4 armed woman with long dirty blonde hair and a mixture of their clothes.
"Will!" Tori's side shouted.
"Tori!" Will's side shouted.
They realized that they're fused into a beast and decided to show the campers. As they got there, the campers got freaked out, "Zoinks," Shaggy screamed in horror, "It's the yowie."
Shaggy and Scooby hid in their tent. "Naga monster," Stitch said, "It's Will and Tori, meega saw Uxie."
Lec clearly recognized Tori and Will too by their clothes and was amazed they pulled a coincidental prank on Shaggy and Scooby.
"Dudes." Dustin said in a shock, "Where did you learn to do that?"
"I accidentally fused with her." Will's side explained.
"You might want to unfuse," Sunny said in her aboriginal outfit, "Someone might think your the real yowie."
There Tori and Will unfused while they blushed at each other. Then Rainbow Dash saw that Lec had a copy of the exclusive Australian magazine, "Monster Weekly Magazine" "Yowie Yahoo kidnaps Matt Marvelous during rehearsal. Most bands will be too scared to perform at this year's vampire Rock music festival."
Fred figured they have another mystery on their hands. Mr. Boy thought it would be a great idea for The Celestian Alliance to investigate Matt Marvelous's disappearance.
