I do not own Scooby Doo. I only own Tiffani and Lexi.

Story Start

Lexi and Shaggy heard the hissing cat before they heard two growls. "Oh no," they whispered before looking at Tiffani and Scooby, who were the ones growling at the cat.

"Tiffani, don't you dare," Lexi yelled before Tiffani and Scooby started chasing the cat around the plane.

"No, grandma, don't eat the kitty," Shaggy yelled and Tiffani laughed when Scooby did eat the cat. Lexi just hit her on the back on the head for chasing the cat. Scooby and Tiffani went back to their seats while Lexi tried to console Shaggy. Tiffani just congratulated Scooby on getting rid of the cat.

The rest of the trip to Spooky Island went without much issue. Shaggy and Lexi were definitely flirting. Tiffani and Scooby were having fun just throwing peanuts at the other people on the plane. When they arrived at the dock for Spooky Island, Tiffani just wanted to throw off her disguise now. She wanted to run around the beach and ride the park rides.

She could tell that Scooby wanted to do the same thing, but he did a great job playing a grandma. Lexi reached over and grabbed Tiffani by one of her paws. "We'll see you later Shaggy," Lexi called out and walked towards the resort. Tiffani waved goodbye to Scooby before she saw him and the rest of the Mystery Inc. be stopped by a unique looking man.

"Who is that?" Tiffani asked pointing at the man.

"Don't point, it's not nice," Lexi said.

"Well how else will you know who I mean?" Tiffani barked and took off her sunglasses.

"Fine, just don't point anymore. I don't know who that guy is," Lexi answered before she checked them into the resort.

The two friends made their way towards the resort and they were admiring how beautiful the place looked. Lexi laughed at how happy her dog looked before she started to notice a difference between the other students. The students heading towards the resort were acting like crazy and happy college kids. However, the kids in line to leave the island were as still as statues. She was also surprised at how orderly their line was too.

"What is up with that?" she thought before Tiffani, who had just stolen a Frisbee from some of the other students that were having fun, distracted her.

"Already causing trouble," Lexi said before she headed into the resort. She knew Tiffani would find her again soon enough after she was done with the Frisbee.

Tiffani ran away from the yelling students with the Frisbee still in her mouth. She looked back to laugh at the angry students and that was her mistake. She crashed straight into the back of a guy that had been standing in the line to leave the island.

"Watch it, dog," the guy in front of her said in a mean tone. She looked up at him and his blue eyes flashed a bright green as he glared at her.

"You watch it," Tiffani said back as she spit the Frisbee out of her mouth and she stood up on her back legs.

"Get off my grill," the guy growled and she growled back.

"I don't smell hamburgers, so you don't have a grill between us or under me," she said smartly and his growl grew in volume. She glared at him before snapping her jaws close to his face. She smirked when he jumped back. "Now shush and leave or make me food since you supposedly have a girl," she said before walking off to find Lexi.

"Where have you been?" Lexi asked a few hours later when Tiffani finally found her in their room of the resort.

"Well I played Frisbee, fought with somebody, I won, then I came looking for you, but I got distracted," Tiffani said before attacking the towels on her bed, which were in the shape of a cat. "Die," she yelled before tossing the now messed up towels into the air. "I win again, I'm on a roll today," she cheered before becoming quiet when Lexi held up a treat.

"I knew that would get your attention," Lexi said with a laugh before sitting on the bed across from her silly dog. "Who did you fight with earlier?" she asked seriously and a little afraid of the answer.

"One of those guys in the line to leave the island and he was definitely a weird character," Tiffani answered before wrapping a towel around her back as if she had a cape.

"How was he weird?" Lexi asked for more details.

"Well he growled at me, his eyes flashed green when they were originally blue, and he told me to get off his grill. He did not have a grill though," Tiffani said with a pout as she imagined all the wonderful food that could be cooked on a grill.

"His eyes flashed green and he growled," Lexi said startled before sighing and saying, "Also, he used some outdated language as well."

"I was really hoping he had a grill though. I wanted to make grilled chicken," Tiffani was whining with her tongue hanging out of her mouth.

"Stop thinking of food and focus for a minute. Something is going on here that does not set well with me. Anyways there is going to be a party later so watch out," Lexi warned the dog, who was giving her a sly look.

"It sounds like you are not going to walk around the party with me, like you have other plans," the dog said with a teasing smirk.

"I met up with Shaggy earlier in the resort lobby and he said he would like to go to the party with me," Lexi answered with a small blush on her cheeks.

"Well I have to find a date too," Tiffani said as she stood up on the bed and let the air conditioning system blow her towel cape behind her.

"Not many dogs on this island," Lexi said before smiling when her dog started coughing awkwardly. "Aw, you're going to go find Scooby Doo," she teased and almost got a pillow in the face.

"Shush, now let's get ready," Tiffani said with a small growl without any bad feelings.

"How are you going to get ready?" Lexi asked with a laugh.

"I have to pick out my best collar," the dog answered before walking towards her luggage. Lexi shook her head when she saw her dog pick out a neon green collar that had Hello Kitty on it.

"You hate cats, but you like Hello Kitty," Lexi said with a raised eyebrow.

"She's not a real cat, but if she was I would want to be her friend. She is awesome. Regular cats are mean," Tiffani answered seriously before taking off the rest of her disguise.

"Won't you get in trouble for walking around without the costume?" Lexi asked.

"Everybody is going to be partying, they will not care," the dog answered before moving towards Lexi's luggage to help her pick out what to wear tonight.

"Ooh, you have competition," Tiffani said with a snicker when the two headed down to the party and they saw the annoying blonde woman from the plane eyeing Shaggy from a short distance away. "Kick her butt," she said to Lexi before giving Lexi a push towards Shaggy, who smiled when his eyes landed on her.

"Hey," Lexi said a little shyly.

"Hey, you look groovy," he said and had a small blush on his cheeks.

"Thanks, so do you," she said and Shaggy held out his hand for her to take. She did so with a happy smile before giving a smirk towards the blonde woman, who was now pouting.

Tiffani watched her friend and Shaggy walk away happily holding hands. "Now time to find Scooby," she said with a smile and she made sure to walk past the blonde woman so she would make her allergies go crazy. When she heard sneezes behind her, she knew she had accomplished her job to annoy somebody tonight.

A cute voice answering a phone call made her stop. She laughed a little bit when she saw an excited Scooby talking on the phone. She laughed even more when she found out he was excited about hamburgers.
