Icheo was running through the forest. The little mouse had a round pink nose, a long tail and a brown fur, excepted under his paws, where it was yellow. The sky was getting darkened by giant clouds and meant rain would come soon. His old, loose-fitting pants and shirt would get all drenched by water and become heavy if he didn't find somewhere to hide soon. Suddenly, the mouse yelped, hearing the thunder, and sprinted even faster. He keeps so until he gets to a rocky area and finally comes to a cave's entrance. The mouse, panting, gets inside the cave, but takes care of not doing any noise, who know what could be inside?
