Mystery Monday: Her Voyage, Part VIII

That afternoon, along a lonely beach,
Where seldom ventured visitors, occurred
The last thing we'd expect. The creature's reach,
Its native waters, are, so I have heard
Entirely unlike where it appeared.
Nor does its kind come often upon land.
It swam the sand and soil until it neared
My sister's home. In haste did Krissy stand
And shoo away -- but 'twas I she dismissed!
"I have to take this" was all that she said.
I left but lingered; just to see what this
Was all about. I watched her shake her head
And wave her hands in anger, so I thought,
But couldn't tell from my poor hiding spot.
