After the helicopter, if I looked straight down there was a white ball which followed me wherever I went, much like a wheel. It disappeared when the next zone loaded. Cat pyramid sounds nice.
OK I get it. I think that is a pill shaped thing that is in the 1st person character. I just need to turn off the renderer of that piece.
I'm thinking riding on a goat or an eagle. There's an eclipse that happens once a year in Antarctica apparently. So giant moon going over the level as you hike.... etc.
