Big Bear is very bored, alone on his ice floe. One day, with his fishing rod in hand, he sees a large piece of ice pass by with a small, colorful thing on it. He has never seen anything like it here! Here, everything is white. Where can this strange thing come from? And hop! In no time at all, Big Bear jumps on the piece of ice and goes adrift with the little red, green and blue thing. This is the beginning of a great adventure to meet new friends and discover wonderful and distant landscapes.
