Water is incredibly heavy, and if we're not careful it sloshes around, pulling us off balance. We tried our best, but once we started climbing we grew exhausted. I slipped and fell.

Somehow my uncle and Hans found me, and dragged me back to the surface. But I had broken bones, and my adventure was over.
THE END
What can we do now? Something that, preferably, does not involve carrying my own body weight in water?
