While the mermaids in "SpongeBob SqaurePants" are more antagonistic (with the exception of Princess Mindy of course, and maybe even the two King Neptunes depending on your viewpoint), I thought about an OC who is a nice mermaid like Mindy, but rest assured, she will never be SpongeBob's love interest, as the late Stephen Hillenberg made it clear that SpongeBob doesn't need a love interest. So in this regard, she's just another friend of SpongeBob. I should also mention that she's not an OC I would use for self-inserts and giving original stories for like when I made Remi Loud (My "Loud House" character hybrid and OC). And while I don't have drawings for her, hopefully you'll get the idea with what I have typed up for her down below.
She's an adult mermaid with yellow skin (much like how the mermaids vary in different skin colors). Like Daphne from "Scooby-Doo!" (as seen as one of my inspirations for Sunny), she has long orange hair. I don't know what color her shirt and mermaid tail would be, so I'll leave that up to you guys in the comments.
Like Mindy, the two King Neptunes, and all the other merfolk on this show (and movie franchise), Sunny has five-fingered hands like us humans do in real life. She has no veins on the back of her hands much like Mindy, but doesn't wear a bracelet around her wrist like she does. In fact, she probably wouldn't wear jewelry at all.
Considering her name is "Sunny", she's beautiful inside and out, but she's adventurous, affectionate, modest, and friendly all at the same time. And though she's friendly on the outside, she can also be assertive and protect herself from harm (much like Lola Bunny and Daphne put together) and has no hesitation to stand up for whoever she's close to like SpongeBob (again, not as a boyfriend/girlfriend dynamic, just friends).
Like Princess Mindy, she's extremely friendly and compassionate as I stated earlier. She can fly around much like Mindy, but when she reaches the surface, she can't fly. Despite this, she can traverse over Bikini Bottom with ease. She can even allow SpongeBob and friends a ride on her back, even though SpongeBob can technically fly with his pants and Sandy with the jetpack on the back of her suit.
Like Daphne, as I stated before, she has the same colored hair and hairstyle.
Like Ariel and Melody, she carries Ariel's adventurous spirit mixed with Melody's determination (like what her father, Prince Eric has.). She also could have a knack for collecting and observing stuff.
Like Snow White, she can be considered "The Fairest in Bikini Bottom", but is modest about her title much like Snow White. And she even attracts animals with her beauty and can have them assist her (For one example, the jellyfish in Jellyfish Fields would easily be tamed by her beauty and they won't hesitate to make jellyfish jelly just for her. For another example, SpongeBob's snail, Gary would enjoy Sunny's company and would know whoever's good or bad, much like Prince Eric's dog, Max, who loves Ariel, but hates Vanessa, who is really Ursula in her human form with Ariel's voice).
And like Lola Bunny, Sunny's will is strong and she's tough when she has to be, even though she's not the "sports" type of girl. So she's more than just another pretty face, as when her friends are in trouble, she has no hesitation to fight.
I've got three options as far as whom I would imagine Sunny's voice. Feel free to comment your opinion on any of my choices.
Tara Strong - Tara Strong's done a lot of voice roles for various cartoons, movies, and video games. If Tara Strong voiced Sunny, I could imagine that she would sound like Melody, albeit aged up to sound like a young adult. Or, she could use her Twilight Sparkle voice for her speaking AND singing voice (as she doesn't do Twilight's singing voice because she's far away from Vancouver, where "My Little Pony: Friendship is Magic" was produced, which is why Rebecca Shoichet does Twilight's singing voice. But here, she can make Sunny's voice sound like how she would've sung Twilight's songs in "My Little Pony: Friendship is Magic".).
Kath Soucie - If Kath Soucie voiced Sunny, I imagined she could use the voice she uses for Lola Bunny as Sunny's speaking and singing voice. Believe it or not, Kath Soucie has sung as Lola Bunny before, particularly in the former Six Flags stage show, "Looney Tunes Dance Off (2010 Six Flags Show)" (for the songs, "Hips Don't Lie" when she sang her duet with Bugs and "Please Don't Stop the Music" to end the stage show with Bugs, Daffy, Sylvester, and Tweety) and in the "New Looney Tunes" episode, "Rhoda Derby" when Lola sang "I'm a Rollerskating Rabbit" while destroying Rhoda Roundhouse's robots.
Kari Wahlgren - If Kari Wahlgren voiced Sunny, I imagined she would use the same voice as the "DC Super Hero Girls (2019)" version of Zatanna. She even proved that she can sing in Zatanna's voice in the episodes, "#SirensConch" and "#HappyBirthdayZee".
WHAT SUNNY CAN DO WITH SPONGEBOB AND COMPANY
As far as learning what SpongeBob does, I have some scenarios I imagined she would do.
If there was a way he could allow Sunny a job at the Krusty Krab, she could either help SpongeBob in the kitchen as far as making Krabby Patties and other sorts of food for the customers. Or she could even get a job as a waitress. Either way, Sunny's natural beauty and her way of attracting customers would create a huge profit for Mr. Krabs. Speaking of Mr. Krabs, he could even teach Sunny about the Krabby Patty formula with or without SpongeBob mentioning a few other details.
At Jellyfish Fields, SpongeBob (with or without Patrick) could teach her the basics of jellyfishing, only to be surprised (in a positive light) by Sunny attracting the jellyfish and maybe even making a playful comment about she's got "the magic touch".
If SpongeBob took Sunny to Goo Lagoon, and introduced Sunny to Larry the Lobster and a bunch of the other beachgoers, the boys on the beach would surround Mindy and admire her. And when it comes to arm-wrestling with her, Sunny would playfully let any boy win, or out of their love for Sunny, they would let her win. In fact, at the Salty Spittoon, Reg might allow Sunny in either because she's beautiful or because she'd be accompanied by SpongeBob or Sandy.
If SpongeBob (with or without Patrick) invited Sunny to come to Glove World with him, I thought SpongeBob could surprise Sunny with a gift. Maybe while she's not with SpongeBob, Sunny could seen trying on different pairs of gloves for her hands, with one pair of course being white wrist-length dress gloves that feel soft and smooth like either satin or silk or any material that's soft. Either way, SpongeBob would give Sunny a bag and Sunny would admire SpongeBob's gift, which would be the same white gloves she tried on earlier. She would put them on and admire that they're exactly her size and thank SpongeBob. From this, Sunny would keep them on as part of her physical appearance going forward (except on some occasions of course). And the next time she goes to Glove World (either by herself or with just SpongeBob or with SpongeBob and Patrick), she would also bring home a boxes of white disposable nitrile gloves (which would feel soft to touch with only her fingertips being textured) to store in one of her drawers with her other clothes, depending on what her home should be like.
Given SpongeBob's love for DC Superheroes, namely Aquaman and Aqualad, I imagined if SpongeBob introduced her to the world of DC Comics, Sunny could be inspired to dress up as Miss Martian, but with Sunny wearing Miss Martian's classic white shirt (with the red x) and blue cape and skirt to compliment her gloved hands.
Patrick Star - She's just as nice to Patrick as he is to SpongeBob, but Patrick isn't in love with her because of his feelings for Mindy.
Squidward Tentacles - She doesn't take kindly to Squidward antagonizing SpongeBob and Patrick.
Mr. Krabs - As long as Mr. Krabs isn't using her as a way to make more money, let alone do any greedy or dirty get-rich schemes, she can be on good terms with Mr. Krabs much like SpongeBob.
Sandy Cheeks - Sandy could develop a gurney or wheel cheer for Sunny to ride on considering she can't fly when she's not in water.
Plankton - Sunny knows Plankton's evil demeanor and knows what he's up to, making her the only "sane" person in SpongeBob's friend group.
Karen - While Plankton's not around, Sunny could talk to Karen about lending her blueprints to Karen's mobile body with arms. Sunny and Karen would be great friends who would be good with sharing secrets. And as far as their friendship, Karen could build a clone of her mobile body for Sunny to keep. And to tell the difference between Karen and her clone, Sunny could have her clone wearing the same white nitrile gloves (albeit four fingered, due to Karen's mobile body having four-fingered hands) she got from one of her visits to Glove World. She could even rename her Karen clone, "Katie", with Katie's voice sounding like Mira Nova (from "Buzz Lightyear of Star Command"), Shego (from "Kim Possible"), Marlene (from "The Penguins of Madagascar (2009 TV Show)"), and Supergirl (from "DC Super Hero Girls (2019 TV Show)"), considering they were voiced by Nicole Sullivan, whom I imagined would've voiced Katie.
Pearl - Sunny is good friends with Mr. Krabs' daughter, Pearl, who would actually envy Sunny, but not in a negative way.
Princess Mindy - Sunny and Mindy would be great friends. In fact, given Mindy's physical appearance somewhat resembling Velma from "Scooby-Doo", I could imagine that if Mindy and Sunny entered a cosplay contest at some convention, Mindy could wear an orange sweater and a red skirt around her tail to resemble Velma, with Sunny wearing a purple dress and a green scarf to resemble Daphne, provided Sunny takes her gloves off first and stores them away.
This is all I've got as far as a character concept, but if you like what you saw, feel free to leave a comment. Even if you comment suggestions for Sunny as long as they stay true to her character.
