"Marina, c'mon, hurry up" Mako urged, roughly pulling his sister's ear with needly teeth before dashing forward on gangly, smoke colored limbs. He didn't want the adults to notice they had gone, and he didn't want what he wanted to show her to disappear before they got there. He remembered the way there, quite easily. All they had to do was follow the snaking curve of the river upstream, and find where a small copse of willows draped their long, strange branches into the water. The strange trees were what had drawn him to the place initially, he'd never seen anything like them before. But he hadn't dragged his slowpoke sister all the way out here just to show her some stupid trees.
Just the day before, he'd seen maybe half a dozen peculiar, dark creatures slip from the bank under the willows down into the water, disappearing in the deep current. What little glimpse he'd caught of them, they looked like nothing he had seen before. Not a wolf, or a deer, or a bird or a fish. He had waited for them to come up, but they didn't come back before he'd grown bored and gone home. Maybe they could breathe water like a fish? He couldn't wait to grab a hold of one and get it to reveal to him all its secrets.
"Here!" Mako barked once he saw the draping willow branches, breaking into a run.
