Pipol Destinations

You like to help people right? Can you help these "pipol" get where they are going? Each and every one must be guided safely in order to complete 20 levels of game play. Be careful not to dig holes too deep because it will kill the person falling in it. Please don't ask me how I know this. Try to dig in a "zigzag" pattern so that no one ends up getting hurt. Thanks for being so helpful!
