In Stitches

The water picked up speed and grew louder. The stream was now a broad, fast moving river. Dash was clinging to a log for dear life; she had been pulled down stream for what seemed to her to be a lifetime, almost drowning the whole way there.
The log was big, maybe it was even a whole tree. She was far too tired to even try to climb any higher onto it, so she held onto it with a death grip as the cold water made her shiver. The water started to slow down, and in a few minutes it was no longer audible. She hoped that the water would get shallow enough for her to walk away.
She took stock of her situation.
"Legs? Check. Nothing new broken? Don't think so..." She moved everything she could think of, checking for breaks, when something landed on her foreleg. She stopped, blindly imagining a flying monster, and began to panic. For a long time she was still with the thing going up and down her water-soaked coat. She became aware of a buzzing noise from her right. There was something over there, for sure. She was scared; the current was trying to push her towards the unknown sound. The small creature took wing, clearing her body with its own small buzzing. To her horror, it landed on the end of her snout. She closed her blind eyes to protect them from this threat sitting on her nose. She slipped, just a little, but enough to startle the creature. She screamed into the depths of her mind as the creature dug a stinger into her snout at the same time, making her lose grip on her life raft.
"OH NO! NO! NO! NO!" She thought to herself as she slipped under again. She flailed to the surface and waved her forelegs around madly searching for something to grab. Her legs hit something. She swung again and again, trying to get a grip on the papery object. The object gave way with a roar of buzzing. Suddenly She could feel dozens of needles piercing her skin making her body light fire with pain.
"Bees! Oh, Celestia, BEES!" She dived under, desperate to be away from the thousands of angry attackers. The undertow caught her and propelled her along the bottom at high speed. She was running short on air, her lungs starting to burn with need. She pulled at the water, trying to get free of its ice-cold grip. Her face came into contact with silt and mud. Her lungs were now on fire. She would need to breathe, to take in the water. Her head broke the surface and she inhaled a breath so loud it literally roared. She tread water as best as she could manage, her breath slowing but not the roaring. It wasn't her at all. It sounded like falling water. The sound kept drawing nearer, the water racing to meet it. She made a face.
"A waterfall... Why me?" She braced herself. She knew these would be the last few seconds of her life. She listened to the approaching roaring, and it made her sick. She almost hoped it would kill her so that this could all end. She got mad at herself. Her friends would miss her if she did something like that. They were probably coming for her, even now. She decided to try to stay alive as long as she could. She tried to swim to the shore with all her remaining strength, the sound of falling water almost on top of her now. She ran out of time and howled in her mind as she went over the falls.
