Helping Others, Being in Charge, Adventure

Mean Merfolk, Bullies, Being Bored

Hello there, human folk! Top o’ the mer-mornin’ to ya! That’s how we say “good day” here in the North Atlantic Ocean. My name is Bryndolyn MacFinnegan, Mermaiden of the Celtic Sea. But most merfolk just call me Brynn. You can call me Brynn, too!

As the oldest royal Mermaiden in my home sea, I get to use my magical powers to help guard the ships that pass by. And I’m very pleased to do so. You see, my special Mermaiden power is the gift of light. Now that I’m sixteen years old,  I can use my light to lead ships safely back to shore when they are lost in a storm. Each night on duty brings new challenges and new things to learn. I shine my light away from jagged rocks and toward places of safety to keep the sailors out of harm’s way. When the nights get dark and the storms get scary, I gather up all the courage I can and shine my light a little higher for the sailors.

I have a silky FinFriend named Fergus who’s been my trusty companion since I rescued him from a fisherman’s net when he was just a pup. He’s a wee spotted seal with the courage of a great sea lion and a heart of gold, so I bring him with me each night to help guide the ships. Fergus keeps me laughing when the seas are gray and smiling through the fiercest storms. He’s been with me every flip of the fin. No mermaid could ever find a truer FinFriend!

When we’re not out lighting the way for misguided sailors, Fergus and I like to explore the deep caves off the coast of the countries Ireland, England, and Scotland. With my gift of light and his great courage, we can really delve into the mysteries of the seas. Tis a fine way to pass a day here in the Celtic sea, discovering treasures in the deep, telling tales of pirates and sea monsters, and exploring new places. We have ever so many adventures, Fergus and me. I can’t wait to share them with you!

For now, keep your lighthouse shinin’ bright!

    I have this tail and I absolutely love it! It’s so pretty with my burgundy bikini top and I love the stretchiness and feel of it. It’s so cute! With the mono fin you can swim crazy fast with it! I love all mermaids and I want to be one crazy bad! I’ve tried so many spells. Have a good day/night/morning/afternoon/evening.

    Ienna says:

    Hi Fin Fun, I live off the coast of East Africa and I met a mermaid who had a bright yellow tail. She didn’t seem intimidated by talking with landfolk– she went up and sat on a rock while talking with them. She has a sea snake as her finfriend, and she is very cold with her words, just like Scarlet before her transformation into Mariana (or is it Maria?) Anyways, I noticed that she seemed to have a power– one moment she was next to me, the next she was gone— then she came back. Is that what you call “teleporting?” Anyhow, I am Ienna and her name was Yvonne. I would be very pleased to show her to the Council, since I guess she has a kingdom that she won’t talk about. All she said about herself and her family was “my father and 2 brothers are dead. It is just my mother and my older brother, Reshen, who keep order alive.” She is like this: dark chocolate skin, bright yellow tail, power is teleportation, likes talking with landfolk and speaking of her late father, dislikes major interaction with other mermaids, personality is reserved, highly temperamental, home sea is the East Coast of Africa around what you all call Madagascar?? Anyways, don’t hesitate to reach out if oyu have anymore questions.

    Till next time, keep exploring and living!

    Hey guys! I just ordered my Tidal Teal mermaid tail! I’m so excited! Ever since i was little, I’ve wanted to be a mermaid and now i can be! Thank you FinFun for making girl’s (and boys) dreams come true with these astoundingly beautiful and realistic tails! We just got an aboveground pool since our local pool doesn’t allow mermaid tails 🙁 So whoever is wishing to be a mermaid, i think that these mermaid tails would be a great investment! (I spent literally all my money for this tail Lol)

          Coral the mermaiden says:

          Technically that is true, but you can be a mermaid without a tail without you legs fused together, they may just really like to swim, I know I do
