There's a serious lack of undersea backdrops without cutouts. It would be nice to have some to go with the wearable sea creatures.

I agree with this. There could be some brightly lit ones too.

I'd like to have some of these, too!

Agreed. Love the but it has the cutout issue and its a little bare.

I'd also love a watery foreground that isn't rain, just blurs/fogs the HA a little so it looks like we're looking at it underwater.
