"What do ya mean there's somethin' living in the friggin' Lagoon, that ol' thing was drained out thousands of years ago" Bunnymund provoked. "Or so we thought" North corrected. "Someone's mysteriously refilled it and is now living there" Toothiana squeaked with somewhat interest. "Let's go check it out" Jack, being the person he is, was incredibly eager to investigate.
(After the sleigh ride to the lagoon and crash landing)
"Well this is absolutely peachy" Toothiana complained at she struggled through thick vines and rainforest before stepping hard on Jacks foot. "Ow that's my foot" Jack had to use all his will power to not scream it at the top of his lungs.
After another 15 minutes of endless travelling they finally scrambled yet fell face down in the sand of the Lagoon. As they got up onto their feet, they all looked toward the Lagoon. For one thing, it was full, and for the other, no-one was in it. Or so they thought. The silence that took place in those last few seconds was very eerie.
The guardians flinched at every sound until Toothiana noticed something unnatural and asked "Ughhhhhh guys, why is that log moving". The 'log' curved itself and disappeared underneath the water. The next thing they knew was that it jumped at them, making them jump back in alarm.
Until they realized it didn't actually jump at them, it just jumped onto the nearest rock. That's when they realized that this 'thing' wasn't even an animal. Well, it was but it wasn't a full animal. The only part major details that they could see was the top part of the thing, which actually human skin. She wore a pure gold singlet like a normal human. Along blonde plait made its way onto the sand beneath the rock that it was based on.
They couldn't quite be sure if it was a boy or girl until it turned to face them. Definitely a girl, it was really obvious. Her big dark blue eyes were filled with pure innocence and for a second, the guardians actually thought she was innocent. Until this happened. Just as Toothiana was close enough to touch her hair, the girl's hair tangled itself around Tooths ankle. She then dove into the water, giving away the other half of her body, a scaly purple tail the length of her plait, also pulling Toothiana in too.
Every guardian knew that the tooth fairy was deeply afraid of the water and so Bunnymund dived in after her. Toothiana was about to pass out of a panic attack and lack of being able to breathe when Bunnymund grabbed her. Just as he was about half way to the surface, the mermaid fought back by grabbing Toothiana's wing and pulling hard on it to try and get him to let go.
By then Tooth had already passed out 20 minutes ago. An idea came into Bunnymunds head. There was a precious music box that she clung to the whole time. He quickly snatched that from her and threw it as far away as possible. But just before he tossed it he read the name engraved on the top of it. Christiana It read in swirly cursive writing. 'Must be her name' Bunnymund thought as he tossed it just as she lunged at him.
He watched as Christiana swam after her possession and then dragged Toothiana to the surface. "Took you long enough" Jack snapped. "Shut it, frostie" Bunnymund said back. "Touchy" Jack muttered. "Well, you weren't the one down there trying to get her off of a psycho mermaid" Bunnymund pointed out.
"I heard that" a voice came from behind them. Bunnymund just about jumped out of his skin as he looked over his shoulder only to see a really peeved mermaid, arms crossed and lying belly down on the rock right behind him. "How dare you throw this away, it could've smashed" She held out the music box for them all to see.
"What's it to you, you don't care about it" Bunnymund almost yelled back. Christiana took this offensively. "Of course I care about this, why wouldn't I, it never used to be mine anyways". "Who's was it then?" Jack asked her. "It was my moms, daddy gave it to her, she told me to take good care of it, she died not too long ago" And with that, Christiana slithered off of the rock like snake in the grass.
