Four friends decided to visit the National Park for the weekend. Their campaign has not only an entertaining, but also a cognitive goal in Hop to Freedom. Friends moved along a pre -planned route and suddenly came across a large cage in which Kangaroo sits and misses. The children were surprised and immediately decided to save the animal. To do this, they need to open a cage, but there is neither a lock nor a keyhole. Apparently, for its opening, you need some special key and you must find it in Hop to Freedom.
