S01E01 The Boy with Six Legs
The aliens accidently lock Tommy out of the lighthouse thinking that Tommy is a misleaded crab.
The aliens find a locked box in Tommy's basement. The aliens say there's something awful about the box but Tommy doesn't believe them.
As if adolescence weren't difficult enough, 13-year-old Tommy Cadle must not only find his own place on the planet but also play host and tour guide to a group of feisty aliens who have taken up residence in the lighthouse where he lives.
