Here's the bit of it that matches the picture. They're in a cave behind a waterfall, if you want to know.

“Hey, do you want to try and jump off that high bit into the water?” Tune said, walking back to the entrance.
“Er, I’m not good with heights. Show me first. Like you have for everything today.” Gaze said. Tune giggled. She backed, and leapt out of the cave onto the rock beside. How did she do it so easy. Gaze could do going in, but not out.
He braced himself, shut his eyes and ran at it. He felt water touch his side, which put him off balance. His feet hit the rock, but one slipped. He was about to fall, and there was nothing he could do. He pushed his feet onto the cliff and leapt. Down, down. He flipped over and went head first. He closed his eyes again, waiting for impact, then splash. He plunged into the water below. He looked around in the water holding his breath. He had just fallen off a cliff into water. That was something.
Gaze let himself sink to the bottom, before using all his might to rocket to the surface. He broke the water, coughing. He’d never been under so long. Coughing, he started to swim to the other side.
Tune ran down the side of the cliff, on the grass, and got to the water’s edge. She stood there, waiting for Gaze to come.
“Gaze! Are you OK!” she said, as his feet touched the bottom and he started to walk up.
“Yeah, yeah, I’m fine. I’ve never done that before!” He replied, shaking himself off.
“I was worried you were going to drown!” she said, starting to walk off. Gaze walked beside her. “I think the original idea was to jump, not fall.”
“Yeah, well I thought that too, until I did fall.” Gaze laughed.
I know, the story AND the picture aren't very good, But I'm 12 years old, and I haven't had too much practice.
