Alex nearly leaped and cheered when the second arrow found its target, burying itself about two inches or so into the Marian's disgusting looking scales. Not much, but it fortunately provided a distraction so that Jim could get to safety. Unfortunately, that distraction was herself. The moment the fearsome creature turned and locked its glowing, hate filled eyes on her, hissing, her excitement faded. The hideous sea creature let out a shriek of anger and held out its hand, reaching for an invisible object. After a moment, water started moving up, forming a broken trident in its hands. However, the tips were still sharp and if anything, the broken bits made it seem even more jagged and dangerous. As soon as Alex realized who it was intended for, she cursed. Shnite.
Then it hurled the trident at her, with a speed that her eyes could hardly follow.
Without thinking, Alex let her instincts take over and she launched herself to the side as it came after her. As she dove towards the ground, the trident passed, barely inches from where she was currently, and one of the tips grazed her side, opening up a slit on her back. Barely moments later, she let out an oof! as she landed in the sand, once soft as silk and now feeling as hard as a rock. Although the gash hurt, she completely blocked out the pain as she got to her knees, wincing as she did it and shooting another arrow at the thing.
"Please." She whispered quietly as she saw the other kid stand over Jim and his hurt leg, while the monster probably prepared for another attack. In the water, she could see a tidal wave starting to form, speeding its way towards them. She was pleading to anyone who bothered to listen. "Please, someone help us. This thing is going to kill us. Help us, anyone."
