Good Frook, you've just spent another night on the planet Crispton! Day 3 was a bit of an ordeal, as one might expect, so today your major task will be to find Eugene. He can can operate the portal so you can return home. If the Frooks above are looking down on you, it will hopefully work.
As with the other games in this series. Find things of use, click around and get things sorted in the right way. Once you puzzle your way through the game you will be in a position to get back to Earth and the very boring life you once had.
