*rubs chin* Weird, I'll look into it. The ring wouldn't bestow water breathing in either case, but it will halve damage from water-based attacks (like the turret crawdaddies). In fact, there are no item that will let you breathe underwater. You could always buy the bikini (if I remember correctly, Keith has it), it gives you normal mobility underwater (but doubles the damage you take), and since the entire underwater area is based around you moving at half speed, it should make it a lot easier to get through. Also, have you noticed hitting a block underwater will release an air bubble? That's not just for show, those will restore your air meter if you catch them.

Hitting a block releases an air bubble? :O
Didn't know that, man!
That explains how I'm supposed to get through these long underwater areas without any air bubbles around! :-D

Well, thanks mate!

Already have the swim suit however the problem was simply the length of the underwater area which I couldn't cross no matter hbiw fast I was.
But definitely gonna play the game again and try the block air bubble thing.
A little in-game hint towards it would be nice :-D

Perhaps I'll be able to find a similarly good solution for the point where I'm stuck at Gun Princess 1 too.
I'm currently in suntown at city hall, at the (hopefully!) last battle.
Which is really hard since I could beat the robot alone only on a dluke, not to mention fighting him and all the other guys together.

You don't know by chance if the gray market is avaiable without winning this fight yet, do you? :-)
