Custom of the Collector edition : repaint/electronics addition.
Wireless, can be charged, the sound comes from the Pod.

You can soothe Lou by rocking it gently, (the same interaction as in the game) but not too hard or you’ll make him cry and light the Pod with a red glow. If the Pod is placed in a dark place it triggers an event : a symbolized BT encounter.This event stays active for 40 minutes or once you place the Pod back in a bright place. Soothing the baby during a BT encounter is also possible.
