Brief Answer:
possibly a mucous string

Detailed Answer:
Thanks for writing to health care magic.
It is normal for babies to pass mucous strings in stools which can have a greeenish hairy appearance.
Do not worry.
Usually no treatment is required.
However if the problem persists get a stool routine test to look for evidence of blood or infection.
Wishing him good recovery
