A small monkey does not let you forget about yourself and here she is again in a difficult situation, and all her curiosity is guilty. Look at the game Monkey Go Happy Stage 151 and you are transferred to an unusual object, an incomprehensible destination. Everywhere machines, mechanisms, levers, buttons, notches. Doors lead to the left and to the right, but nothing works. Make the gears spin, light the bulbs, find and install the necessary parts. Only after complete repair and restoration, you will understand that it is in front of you and where the restless monkey climbed up. Solve puzzles using logic and savvy.
