You rub your eyes and look around. It's cold and dark. Where are you? You quickly realize that you have appeared in the zoo at night! Walking in the crisp snow, you recognize the entrance with its polar bears, the lake and the big rock, but the animals are nowhere to be seen. Instead, you meet a variety of different creatures. One of them turns to you to ask for your help. You must carry out a mission for which you are given a map showing a part of the zoo in detail. Based on this, and going via certain points in the zoo, you need to reach the final stage of your mission. The task seems easy, but the strange creatures that pop up and the blizzard howling around you make it difficult to navigate. Fortunately, if you listen carefully and manage to memorise all the stops on your journey, you can succeed in your mission. Meanwhile, the others are also wandering around the zoo. Which of you will achieve your goal first?
