Manuela Poem by Ima Ryma

Once upon a time, as a pet,
Lived Manuela in a home,
As a tortoise, and she was let
Free throughout the household to roam.
One day she up and disappeared.
The family searched high and low.
But she was gone. But then the weird -
Thirty years later, who does show
Up in an unused closet? - same
Manuela - joyous laughter.
And out of the closet she came
To live happ'ly ever after.

Put on the fact or fiction scale,
Is this a tortoise fairy tale?
