GG with atmosphere?

[andrewg_oz]

I don't think I've seen one of these before where a GG has the blue atmosphere indication?

The only difference I can see from the other GGs in the system is its atmosphere has three components listed, while the others only have two.

There's no question here, I'm just sharing!

I believe that's a Water Giant. Water Giants always seem to have those indicators since Odyssey. They have their own entry under the gas giant category in the codex. As far as I've seen they're the only type that show them.
