Our heroes were in the Infinite Ocean, hoping they can get their mermaid transformation spell right. "All we have to do it say this Ligea Lyric spell"
"Ligea" Ruby said, "Wasn't she Aisha's aunt."
"Yes" Bloom replied, "And the same woman who gave us our mermaid power."
"Now" Stella smiled, "What is the spell again?"
"Mermadina, mermawinx, mermawonx" Ruby shouted as they turned into mermaids.
"Look at us" Rosie smiled, "We're mermaids."
"But, what about Donna" asked Vulcana
"Magic!" shouted Donna as she and her friends jumped in, turning into mermaids.
"I think she's got it" Ruby replied, "Now what do we do with our special mermaid powers?"
Ruby made the water cold, Rosie turned into a dolphin and turned into a mermaid again, Vulcana made underwater flowers grow, Joanna made underwater tornados, Namira made a few animals fall asleep, and Pamela made some saltwater taffy.
"Wicked" Joanna shouted, "These powers are cool."
Rocket was on the boat minding his own business, that's when he decided to do some fishing while the kids are off doing mermaid magic.
Little did they know, is that the Twinasties were in a sea cave, looking for a special pearl. "Where is it, where is it" Devi asked in panic.
"Sis" Deville replied, "It's just a pearl, what's so special about that?"
"Deville" Devi replied, "This isn't just any pearl, years ago, The Trix, Politea and Aisha's wicked cousin, "Tritannus" almost tried to defeat the winx club with it."
They found the clam that kept the pearl. Deville tried to open it, but nothing worked, "Come on you stupid clam" Deville shouted, "Open this minute you idiot!"
"Did I forget to mention that it can only be open with someone by a good heart?" Devi asked
"You did" Deville, "But where are we going to find a pure-hearted mermaid at this late hour?"
Then they realize something, if they can trick the Sparx Club into opening the pearl, they can get it for themselves.
