Gubble is a loveable alien who has a purple head and a red body--but he has become separated from his family and the alien mother ship. Can you help him find his way back? The idea of the game is that you have to use your wits, as well as a large range of tools, to remove the nails, screws, and tacks from dozens of varied levels. But be warned: There are lots of nasties loitering around to try and stop you from reaching your destination.
