Yes, yes there is water on Zebeth. Not nearly as much as compared to Earth, but there are indeed underground grottos and other water-related pools and such. There's gotta be... how else would there be snow or vegetation?-
YES! WATER! SWEET, MERCIFUL, REFRESHING, BLUE WATER!
<Eh, why get when when I can just wait this one out.>
Metroid, Samus, Kraid, and the rest of 'em are all property of Nintendo, who to my knowledge wouldn't do anything such as sue me or shut poor Planet Zebeth down, because they're so damn nice, and Metroid kicks ass : }
This particular comic strip was made solely by me, by that happy little program known as KolourPaint. Yes, the one that everyone runs in fear from. That's why the comic looks the way it does.
