The Penguin has to go home by crossing the river without falling down. Help him reach home safely, within the given time, carefully avoiding any obstacles on the way. In the last three levels, you have to help two Penguins. Do not let the Penguin fall to avoid playing the same level again. Complete the level and move on to the next levels.
