Our heroes were in Cap Cod for the 100th Annual Mermaid Festival. Mermaid decorations were all around the town and everyone was celebrating. "Can you believe that we're here at the 100th Annual Cape Cod Mermaid Festival?" Isadora asked. "I've seen reports of it in the newspaper, like the ones Tia Delfina read sometimes while working. There was this one time where a town darling who's also a Miss Massachusetts pageant winner came in wearing the same dress that won her crown."

"Easy, Isa," Addison replied. "We're not only here to celebrate the Mermaid Festival, but we're also staying at Will's beach house so the mortgage won't foreclose."

"Will has been thinking about using that as her honeymoon cottage, too," Mahi explained. "She's trying to save money to renovate the pet daycare and for her upcoming wedding."

"We should help renovate, too," Peggy suggested. "Maybe some frog prince wallpaper and some pet food imported from Ireland."

Back at the beach house, Will, Matt, and Alexa were giving out food to some water fairies who will be staying with them. "So after the third time is up," Will said, "you guys will be staying here?"

"That's right," answered a water fairy. "Someone's gotta keep Magical Realty going."

Alexa was confused, because how could a bunch of water fairies take care of a beach house? Will explained to her that Magical Realty was a government-covered real estate company, to make sure that magical creatures had a safe place to live. They also covered homes in Lititz Heights, Rosewood, and Gravity Falls.

"That makes sense, Mom," replied Alexa. "And isn't that the same real estate company that got our house?"

"It is," answered Will. "Soon Matt will be moving in."

Back at the festival, the girls were enjoying some cole slaw when they spotted a strange float with some grey devil like jellyfish. "Wait a minute," whispered Peggy. "Those are Jeivan jellyfish."

"Their going to zap the patrons!" exclaimed Rayne.

By a Princess Dynamite Patrol float with a broken tire, they hid under it and transformed.

Guardians Unite

After they came out of the float, the Jeivan jellyfish ran amuck. Under the disguises of safari people, the five of them revealed to be Vinod and his crew. Mahi was petrified because her own brother wanted to sabotage a festival. "They get this way every time a festival comes to town," she groaned. "They purposefully scare away patrons with cheap floats and scary masks."

"Have you ever been involved in these?" asked Addison as she did a flower shot.

"Once," replied Mahi. "Unfortunately, they think my guitar wails were too distracting."

"Lookit here, Vin!" shouted Karenna. "The runt and her friends are here!"

"What are we waiting for, guys?" asked Vinod. "Let's give that little traitor the stinging of a lifetime."

Not wanting to get stung, the girls flew off to the beaches. While flying around the waters, they saw a giant shell. Out of the shell came Queen Diondra. She was wearing a beautiful purple mermaid dress and a plenty of pearls all around her.

"Queen Diondra," recalled Peggy.

"You look pretty," commented Addison.

"Thank you," replied Diondra. "My subjects always come out during this day."

"You heard about the festival?" asked Rayne.

"Everyone in my kingdom does," Diondra answered. "In fact, we pull off a float every year so we can see humans. Fortunately, everyone thinks that it's all costume and effects so we won't get in trouble. We mermaids hide in the depths to avoid capture."

"That's good," answered Addison. "We don't want to see you guys get dissected."

After explaining to her about the Ferociars' little act, Diondra became annoyed. "You guys take care of those mermaid-nappers," she advised. "The water fairies and I will get our float ready."

Worried that the festival would get ruined completely, they decided to go back and face the Ferociars.

Back at the parade, Lua Doi was inspecting their poorly made float. "You had to go through the Jeivan Empire dump," he guessed.

"We love dumpster-diving," admitted Ragoba. "It's how we get our stuff."

"Unlike that lame old guitar Mahi found when we first came here," Jyoti replied. "I mean, she taught herself to play and she learned how to repair it herself! Lame!"

"We were better off without the runt," admitted Dhraya.

"Boo-hoo!" shouted Mahi from behind. "I kind of miss being in a family. Oh, wait - no, I don't."

Using her fireballs, she scared away the Ferociars and burnt the bad float until it was all ashes. Luckily, everyone cheered because no one wanted a cheap float.

After Lua Doi and the Ferociars went back to the Jeivan Empire, Addison fixed up the floats with beautiful flowers. Everyone was so busy putting out the fire, they didn't notice the girls rebuilding the floats.

As they were cleaning up, a bunch of water fairies came up and painted prettier decorations for the float and lead the girls with their blue glittery trail.

Quickly, they hid behind an underwater-themed float and changed back. As they were about to leave, a group of water fairies appeared and requested to join them on the float. Not wanting to upset them, they decided to do it. On top, they met Queen Diondra, who was given a magical spell that prevented her from being dehydrated. "Nice job saving the mermaid festival," she commented. "I don't know where I'll be without you girls."

"No problem," Peggy replied. "By any chance do you have any instruments? I believe Cape Cod could use a little Rockin Bonanza power."

"Yeah," replied Isadora. "I know that my boyfriend Dagger and his sister Merula aren't here, but we can still be Rockin Bonanza. Peggy and Rayne are honorary members because they formed a bond with us since they came here from Ireland and Boston. Mahi, on the other hand, was homeless until the spray-painting incident at our school, where her big brother and his friends turned the music wing into their own art studio and she was responsible by giving them the inspiration of graffiti at school. As punishment, she was forced to join the school's ballet club and help raise money to pay for damage."

"Technically," answered Diondra, "some of the water fairies have made instruments out of shells for you."

Behind them, they could see a guitar made of seaweed and clam shells, a keyboard made of an oyster shell, and drums made of snail shells. Also, Will, Alexa, and Matt were waving towards them. "I get to play on the snail shells?!" Isadora exclaimed. "Another name for snail shells is escargot. I knew Mr. Covington has had snails before, and he's the only one in his family who likes them. Mrs. Covington hates snails; she couldn't risk the flavor and believes they're not for eating. Growing up in Jamaica, she knew a lot about shells."

"You also get to dress as the Spice Girls," Matt answered. "We need to let these folks remember the 1990s."

"And you would not believe the tribute band from the UK who are now models for Kittybug Fashion in Paris," Alexa replied.

Later that day, they were performing Spice Girls' "Viva Forever" while dressed as the Spice Girls. Peggy was dressed as Baby Spice, Rayne was dressed as Sporty Spice, Isadora was dressed as Ginger Spice, Mahi was dressed as Scary Spice, and Addison was dressed as Posh Spice. After the performance, Addison realized something. "There's something familiar about that Lua Doi guy," she admitted. "I just can't know what it is."

"Never mind that now," replied Rayne. "Let's spice up our life!"

"You're right," agreed Addison. "We can't be downers at a mermaid festival."

Lua Doi took off his mask and revealed to be Duy Can, Addison and Mae's father. Though he wasn't a bad man, he was brainwashed by Asinorth's music into doing evil biting. "You can be normal by hearing the Vietnamese words for I lo-" shouted Zemunth as Asinorth covered his mouth.

"Go check on the Jeivan dogs!" shouted Asinorth.

The brainwashed writer started to get a little confused.
