Wild animals love freedom and no matter how comfortable they are in well-equipped zoos - this is bondage. It’s dangerous to be free at times, sometimes you have to go hungry, but at the same time you can go wherever you want, and not remain an eternal object for the entertainment of two-legs. The hero of the game Stacky Zoo decided to escape and ask you to help them. They did not think of anything else to perch on top of each other, creating a tower that would be higher than the fence surrounding the zoo. Your task is to pile up the animals on top of each other so that the tower is as high as possible and does not fall.
