In a part of Beach City, Ben, Lea, and Donna were getting some peanut butter and jelly sandwiches from the local sandwich shop, Dennis's Delights, when two girls on rollerskates came in. Luckily, they didn't drop their sandwiches. "Sorry," the biracial Pakistani girl said. "We've seen people rollerskate on the beach on TV, and we thought we would try this for real."

"It's nothing compared to rollerskating in Chicago," replied the African-American girl.

"You're from Chicago?" asked Donna. "I know a guy from Chicago."

"Donalie," Ben said. "You shouldn't talk to strangers, young lady."

"It's okay, Dad," Donna replied. "I can tell they're friends."

"I'm Kasdy," greeted the biracial Pakistani girl. "This is my best friend Molly."

"I'm Donna," Donna greeted. "What brings you to Beach City?"

"We're the winners of 'Remember Dennis the Duck'," Kasdy replied. "As grand prize, we get to spend a week here in Beach City and meet the creator's great-great-grandson and the place where Dennis the Duck got started."

"Dennis the Duck?" asked Donna. "Who is that?"

"He was a cartoon character in the 1930s," Molly explained. "After 100 cartoons, he stopped in 1950. My parents had all their cartoons on DVD and collect memorabilia of them. Plus, we remember their catchphrase."

"Have a sandwich!" both Kasdy and Molly shouted.

Little did they know was that Spinel placed some chemicals into Ben and Lea's sandwiches.

CLST and the rest of their crew came up to the Solos to check out Dennis's Delights. Out of the shop came a middle-aged man wearing the signature Dennis the Duck hat. "Hello," he greeted. "I'm Dominick Vance, great-great-grandson of Dennis the Duck creator Karter Vance."

"I can't believe it's him," Kasdy whispered to Molly. "We're in the presence of Dennis the Duck's creator."

"I know," Molly whispered.

"Now which one of you lucky people is Molly Avila?" asked Dominick.

"I am," Molly answered shyly, "I brought my girl Kasdy, and our chaperones, her brother and sister Argin and Evin, are checking out the food festival and they don't want us to overeat."

"Words of wisdom from your big siblings," replied Dominick. "Now tell me what you know about Dennis."

"What I remember from my parents is," Molly replied, "that Dennis the Duck works as a plumber in the town of Panini Town. His girlfriend is widowed Colette the Chicken, who owns a sandwich shop and gets help from her 24 chicks. The most famous of them all is the adaptation of 'Snow White', where Queen Wolfarrah gets jealous of Colette's beauty and caring nature. Dennis always pranks on his enemies, mimics them to their annoyance, and especially tosses sandwiches."

Everyone was amazed by how Molly knew so much about Dennis the Duck.

"Sandwiches are Dennis's favorite food," recalled Kasdy. "Tuna, turkey, peanut butter and jelly, grilled cheese, ham, meatball, ice cream, pastrami, sloppy joe, fluffernutter, BLT, chicken salad, bologna, hot dog, taco, or hamburger."

"Hot dogs, tacos, and hamburgers are a type of sandwich," Poe recalled. "Plus I'm getting hungry."

Everyone walked into the restaurant, except for Coco, Inferno, Daydream, Virtual, Stitch, and the laser puppies due to a strict no-pet policy.

Inside the restaurant, Dominick handed out some free samples of turkey sandwiches with grey spices on them. But through the partially opened door, Coco, Inferno, Daydream, Virtual, Stitch, and the laser puppies could sense there was something wrong with the sandwiches.

CLST, Star, Lilo, and Tucker weren't hungry, because they were saving their appetites for the festival later on.

Rey, Finn, Poe, and Rose took a bite from the samples while Ben and Lea finished up their sandwiches. They froze for 10 seconds and started to get some migraines. "Are you okay?" asked Star as she started comforting Lea.

"Who are you?" asked Lea.

"Good one," laughed Star

"No, really," replied Lea. "Who are you?"

That's when they knew - the crew had amnesia. As Molly turned her head, she spotted a walking bathtub sneaking through the shop. "I know only one cartoon character who uses bathtubs as transportation," she said.

They followed the bus to the side of the store. Star squirted some mustard on the curtains to stop it. After the tub got hit by the mustard, a 1930s-styled duck came out of the tub and complained, "Now I gotta clean my bath curtains."

"Dennis!" Dominick growled. "What are you doing?"

"You were so busy preparing for the food festival," Dennis explained, "I decided to go to the Crystal Empire in Equestria. It's amazing what little pencil magic can do."

"Toons," growled Lec.

"While I was exploring the outskirts of the empire," Dennis continued, "I met Spinel, who was skulking around and playing with roses. So I thought-"

"You would take her to the human world and play sandwich pranks," Dominick guessed, "including giving some customers a little food poisoning with Wolfarrah's amnesia potion."

"Yeah," replied Dennis. "How do you know?"

"You always cause trouble for others," Dominick replied, "especially your toon nemesis - Fletcher the Fox, a down-on-his-luck actor-fox who would do anything for attention."

Spinel popped out of the tub and started using pepper shakers as maracas. "You know what would make Spinel less creepy?" Sunny asked as she sneezed. "A hug."

"Sunny," Lec growled to his sister, "that won't work."

"I haven't tried that," Dennis answered.

With one hug, Spinel changed back to hear cartoony self. The only thing left now was to get rid of the mess.

Kasdy held her amulet and summoned her Gemini power, which meant wind. Everyone was surprised that Kasdy has superpowers. "This is the Amulet of Asteria," she explained. "A while back I earned it after little hobo trouble and a little museum troubles."

Just then, they noticed that their crew had gone missing. "Now we gotta get our crew back to normal," replied Cho. "I'll go after Ben and Lea, Sunny and Lec should go after Rey, Teal, Tucker, Star, go after Finn, Lilo and Donna, go after Poe, and Kasdy, Molly, Dominick, Dennis, and Spinel, go after Rose."
