How do you get familiar 7? A few of my friends and I have explored everywhere and aren't sure if we missed it in a room or what.

I think familiar 7 is either the bubbling or ghosting u one, either way here are the two solutions:
1). For Ghosting U, you need to grapple the green, spectral grappling point on the island for 10 seconds or so, maybe a bit longer. It's near the temple.
2). For bubbling, you need to go to the fatum room (accessed with the beast on top of the temple) and sit in the pond for a full minute. The unlock condition for this one is annoying, so that's why most people don't end up getting this familiar.
