Cocoon

Cocoon has 11 total collectibles known as Moon Ancestors. These can be acquired as you play through the game, or easily mopped up using chapter select once you finish the story. They are most often hidden just off the main path; may involve a small and simple puzzle, and are unlocked with an interaction.
1:30 - 27% - Mesh Network
The Mesh Network collectible can be grabbed shortly after going through the large door. Use the node to rotate the bridge 3 times. This allows you to find a hidden path going down and eventually leading to this moon ancestor.

Relatively early in the game, you will be working with a portal that lets you place either an orange orb or a green orb into the middle and you can then jump in.

You will progress with this portal for a while as part of the main progression. You will be at the correct point for this achievement when eventually the small robot companion docks into some blue capsule and opens the door heading north.

Now, whilst carrying the orange orb, go into the next room and use the switch to rotate the satellite turret to the south-west (bottom left) corner. Follow the path now created to reach the Moon Ancestor.
