"Although they spend most of their time in water, the drop in barometric pressure that occurs when it rains causes an air sac within these octopus-like monsters to inflate and lift them into the air."
—Hyrule Compendium on the Water Octoroks, The Legend of Zelda: Breath of the Wild
"These low-level, octopus-like monsters used to be aquatic, but their inflatable air sacs evolved so that they are able to float around in the air. Other monsters are known to take advantage of this ability, using them to make floating fortresses. They are trained to ascend when they hear a whistle but they will not attack."
—Hyrule Compendium on the Sky Octoroks, The Legend of Zelda: Breath of the Wild: The Master Trials
"This species of blowhog uses internally generated hydrogen to inflate a flotation bladder and hover above the ground. The creature's electrified pulse creates a sash of color that flows along the surface of its body, making it a particularly beautiful blowhog species. Precisely how it is able to internally stabilize its highly explosive hydrogen and simultaneously generate electricity remains a mystery. The puffy blowhog blows leaves and grass around to eat the insects underneath. It maintains midair buoyancy by using its fins and releasing air through blowholes. This enables it to float effortlessly, even in the breeze. In times of danger, the puffy blowhog can decompress its flotation bladder for a rapid escape from predators."
—Olimar's Notes on the Puffy Blowhog, Pikmin 2
Floating downwards from a great height there came a purplish patch of vapour, small as I saw it first, but rapidly enlarging as it approached me, until it appeared to be hundreds of square feet in size. Though fashioned of some transparent, jelly-like substance, it was none the less of much more definite outline and solid consistence than anything which I had seen before. There were more traces, too, of a physical organization, especially two vast, shadowy, circular plates upon either side, which may have been eyes, and a perfectly solid white projection between them which was as curved and cruel as the beak of a vulture.
The whole aspect of this monster was formidable and threatening, and it kept changing its colour from a very light mauve to a dark, angry purple so thick that it cast a shadow as it drifted between my monoplane and the sun. On the upper curve of its huge body there were three great projections which I can only describe as enormous bubbles, and I was convinced as I looked at them that they were charged with some extremely light gas which served to buoy up the misshapen and semi-solid mass in the rarefied air. The creature moved swiftly along, keeping pace easily with the monoplane, and for twenty miles or more it formed my horrible escort, hovering over me like a bird of prey which is waiting to pounce. Its method of progression—done so swiftly that it was not easy to follow—was to throw out a long, glutinous streamer in front of it, which in turn seemed to draw forward the rest of the writhing body. So elastic and gelatinous was it that never for two successive minutes was it the same shape, and yet each change made it more threatening and loathsome than the last.
