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.

The CyberSquad attempts to create a nest similar to that made by the Tiki Bird so that they can hold an egg in it.
