Did you know that fish in our rivers are real adventurers? They travel enormous distances in search of food or a safe place to lay their eggs. But their journey is not without danger... Along the way, they encounter powerful pumps. These pumps are extremely important for keeping our land dry, but for fish they are a difficult obstacle. In this life-size floor game, you become the fish! Form a ‘school’ with your friends and race across the river to the sea. Which pumps are safe and where do you need to be extra careful? Will you manage to reach the finish line before the big Sea Gate closes?
