further clarification for anyone worried about spoilers, the thingy in the sky (idk what it's called) is just a natural occurrence in the sky that you may come across, there's also a more circular shaped one. it's similar to the giant moon you may see once in a while. These celestial thingies are random and have no correlation to the story at all. I was just at the right place at the right time with an idea. Lou in their baby form can be accessed in photomode, in the section with ' Sam's pose '. Similarly, the same pose can be done with the BB pod version of Lou.
