The Legend of Zelda does not belong to me, or else this would be canon.
Billy the Bokoblin was having an alright day. He'd managed to catch 3 Hyrule Bass, which had fed him wonderfully. Happily, he looked to the sky, hoping that the rest of the day would go well too. That was not the case.
With a couple slashes of a Traveler's Sword, Billy's horn and fangs quickly went into the hero's inventory. Link, the hero of Hyrule, looked around before checking his Sheikah Slate. Confirming he was headed in the right direction, he nodded, and continued off towards the Zora's Domain.
He'd been there before, and knew how to defeat all the enemies, so it should have been a piece of cake to get the package to Sidon. Unfortunately, the rain was quite a bit harder than it was the first time he'd been through there.
This struck him as suspicious, but he soon chalked it up to him arriving in the Zora' Domain a good deal earlier than last time. Still, however, the heavy rains made it a good deal more difficult to see ahead of him, and made even the most mundane of paths treacherous to traverse.
Suddenly, as he was following a thin path up a cliffside, his foot slipped on a rock. He tried to regain his footing, but the path was to wet to even grab onto, and the hero went swift into the cold waters of Zora River.
Struggling, he tried to swim too, but to no avail, as the rough currents of the river carried him fast and strong. To make things worse, he hit his head on a rock, blacking out.
