Obo Obo no Mi

Appearance
The fruit looks like a dark blue melon with spirals on it.

Powers
The fruit allows the user to create and control a breathable liquid, making the user a non-drowning human.

Usage
The liquid created by the user is unable to drown anyone caught inside it and rather actually enables one to breathe better when inside it because of it's surplus of oxygen and easiness of removing carbon dioxide and other waste products of cellular metabolism through breathing. As such encasing anyone inside the liquid will allow them to breathe better instead of drowning them as would be expected.

The coloration of the liquid itself seems to change as the light levels change and air composition, it can be seen as a clear dark blue to a much lighter almost cyan clearness to it.

The liquid itself doesn't seem to react much more then with air and will generally be unable to put fires out quickly and objectively, it can however be phase changed with enough technique into a solid, tho it loses it's breathable properties and the user loses control of it. Melting it does not give the user control again, instead it makes it disappear.

Weakness
The user suffers from standard DF weaknesses.
