In Pipes

There is no sign of the creature Lisa. Three friends, Marvin, Shrub and Dod, who would be the only ones to realize that she is gone go looking for her. This takes them out of their sector which is part of a world that has no sky only pipes. As they do so they find themselves in the infested world of pipes which can have many paths and dangers all around. As they make their way into an area that does not have pipes, The Wide Areas, the three find out where their friend has been all along.
