In [i][[Kantai Collection]][/i], enemy lifebuoys are one of [[Escort Water Princess]]'s four kinds of companions, the ones that make part of her belt(?). They also often appear along with [[gambier bay (kancolle)|Gambier Bay]], being the unabyssalized [[Escort Water Princess]]. Their unexpected popularity essentially turned them into mascots for the Abyssals and the series in general.

They are essentially Abyssal Lifebuoys, with a toric body, short but thin limbs, protruding horns and an expressive mouth. They come in several colors. [[Escort Water Princess]] is featured with white and red varieties, the ones featured in Mizuho's summer art are in her usual chartreuse, and the ones in [[Gambier Bay (kancolle)|]]'s [[Lawson]] art also appear in striped varieties.
