Will and his brother Robby have met more than their share of aliens in the past -- they come, they eat dinner, they leave -- no big deal. But their latest guest, an alien named Saliva, has some earth-shattering news. Will and Robby's home is to be an intergalactic resort for space travelers: Club Earth. At first Will and Robby are thrilled. They'll be the only people on Earth having aliens sleep over. But after a while, playing host to an endless parade of odd creatures starts to get a little old. Luckily, Robby and Will come up with a plan to send the aliens packing.
