 Will and Holly are out harvesting food when Rick signals them using one of the mirrors they all wear around their necks. When Will is signaling back, he accidentally flashes one of the pylons. To his surprise, the pylon flashes back. When Will goes to try and catch a pink and blue chicken, Holly sees three diamonds twirling around in the sky by the pylon that flashed at Will. Will and Holly go to investigate the pylon and Will manages to get the pylon to open up, revealing a chamber inside. In the center of the chamber is a tray filled with illuminated colored crystals. When Will and Holly start touching various crystals, the weather outside begins going haywire. The dinosaurs become agitated and Rick goes in search of Will and Holly. He finds them and they tell him about the pylon. The twirling diamond reappear above the pylon, flashing the colors of the crystals that Will and Holly had touched. Rick leads them back to the pylon, they all go back into the pylon and push the crystals again in the order of the colors that the diamonds are flashing. Once they complete the sequence, the weather returns to normal. The three exit the pylon and Will closes the doorway. Rick warns the children to be very careful investigating things in their new home.
