Nick and Sally went to the zoo and found there fascinating attractions - riding from the hill. What is most surprising is that the height of the slides can be adjusted by removing or adding extra blocks. In the park, the heroes met cats of twins of an indeterminate kind and decided to organize competitions on descent along the gutters. An unchanging friend - a cat with a hat that accompanies children, will give assignments, and you help them to fulfill. Sometimes you need to let the opponent win or come to the finish line at the same time in Slidea-Ma-Zoo. Change the height of the lift, add different accelerating or slowing objects, they can be found below the horizontal panel.
