The woman who walks the most famous turtle in New York City reported for duty at his home in Harlem on Monday afternoon.

He had left her a large present in the apartment hall and was leaving another in the kitchen.

“Thank you, buddy,” Amalia McCallister said to Henry, the African spurred tortoise, also known as the Notortoise BIG on his Facebook and Instagram accounts. “I really love that.”

Ms. McCallister, who recently beat out hundreds of people to make $10 an hour cleaning up after a reptile the size of a roasting pan, was unfazed. She swabbed Henry with baby wipes, rubbed turtle conditioner into his bumpy shell and pointed him toward the door.

Henry, surprisingly agile for a 17-pound tortoise, raced for the exit. Ms. McCallister locked the door behind him and carried him down two flights, mindful of his legs, armored with spiky scales, and the possibility that he would soil her long blue dress.
