When Smith uses all of the potable water for a shower, he forces the Robinsons to search for a new water source. They find it, in the form of fruit that grows in a brackish well. Unfortunately for Smith, he eats it before Professor Robinson has a chance to test it. Smith runs off, sure the Robinsons have purposely poisoned him, and takes the last of the working fuel cells with him. Unbeknownst to him, he turns into a paranoid giant overnight.
