So...

 You think you know her
but her enormity of moods
proclaims you do not
that you could never know
as she tickles your toes on the beach
where the next dead whale will founder

Without notice
she might gather her skirts
and rush upon you in a rage
piling high the lump in her throat
drowning the fires from some quake below

So could you ever be safe
your hotel balcony
sits on the third floor
but once
she swallowed mountains
and all the world grew fins
