Snorkle sounds. No hints there. But, the yuureidoushi says it's Nagamon in the comments (in response to a comment saying that it's hard to work out who they are without the headgear or equips)
Looks like Nagato's puchi? At least the tags on the source only mention Fubuki, Yamato, Nagato and Yukikaze.
it's yukikaze's puchi. In the anime nagato encounters a squirrel in that scene.
I've been soaking here for close to an hour already...Bathhouse
–Exclusively for Puchis'though... this bath is really cramped.Hmm?The strongest battleship, Yamato-san, and her puchi Hotel-chan...She got friendly so fast...I wonder if her puchi is also the strongest after all?Speak of the devil, it's Hotel-chan.How odd... the destroyer girls ought to have come by now...Hot...It's cold, so get over here, quick!
