During a sunny day, W was walking in the depths of the forest in order to collect some apples for the dinner. She suddenly found herself between some bushes, trying to pass though the density of the forest, ending in a little pit of mud. At the start, W just walked on the mud with ease, it wasn’t deep enough to let her sink. But this was a careless action, because in a simple step, W ended with her whole leg trapped between the mud’s pressure. She started to struggle to get out of the sticky mud, but she only get her right leg and her hips into the mud’s grasp. The fight it’s not that effective, so she starts to search another way to escape. W saw a vine hanging in a tree, so she starts to struggle, pulling with one arm, with the hope of reach that vine and get out of that sinking trouble.
