I have this idea for a sequel. It might be based around this image here:
Could possibly include new characters like Kema's family. It includes her younger brother Levi, and their widowed mother Kirina.
Can you imagine Lincoln doing sex with Kirina? Probably, seeing how hot she might be as a mermaid, or in her seashell bra and exposed belly with legs in place of her tail and a skirt covering her waist. She's in that form alongside Levi in an image where they meet the Loud family.
Maybe Lincoln could do something sexual with Red(who hopefully gained permission from Serena, and doesn't want to pull the same stunts Iris was pulling).
In case people like CrossoverWeasel16 haven't looked at Red's bio, the description says this:
Relatives: TBA
Friends: Lia, Abilia, Iris
Enemies: TBA
Personality traits: Shy, Loyal, Creative, Curious, Helpful
Likes: Whales, Dolphins, Bubbles, Seahorses, Manatees, SpongesDislikes: Sea urchins, Jellyfish, Sharks, Ink
Here's the actual bio: Red is a shy, red-haired mermaid who just want to make new friends. A lot. Red always afraid of sharks, volcanoes, and pollutions. She loves to take selfies with Lia above the surface, chat, and most of the times, sleepover. Red cannot handle fear.
