Spider's Mysterious Friends

Having been swept down a river after several days of heavy rains, a lone spider climbs ashore and finds himself in a place that is completely foreign to him. Tired and confused, he seeks shelter to rest from his ordeal. Upon waking several days later, he finds himself in a different place, then he remembered when he first arrived. When he decides to leave his shelter to start exploring the area, he finds that he is trapped and unable to move.
