The CyberSquad attempts to create a nest similar to that made by the Tiki Bird so that they can hold an egg in it. When they have difficulties holding the nest together, they believe they should use glue, but Creech shows them part of a nest that a Tiki Bird made, and it doesn't have any glue. They identify the pattern of the strands and replicate it to create a nest.
After building a nest for the egg, the CyberSquad builds a leaf canopy to protect the nest from the rain. They try weaving a roof with the same pattern as that of the nest, but it doesn't work, as it lets rain through. They find a tree with a leaf pattern that slides all water off to the side and replicate the pattern to create their canopy.
Mark records a video log in which he discusses a challenge to his survival: he'll run out of food unless he grows more. He needs to figure out a way to grow 3 years worth of food on Mars, where nothing grows. Instead of feeling hopeless, Mark shows that he is ready to take on the challenge.
