The Phillie Phanatic was on hand to surprise the girls and their mother with a custom-made swing set, as well as Adirondack chairs for the grownups and even a new doghouse for the family's new puppy.
The girls, 4-year-old Izzy and 11-year-old Grey Hoffman, recently lost their father, Lou, to a rare disease.
The Phillies brought in the team's landscaping crew to add a garden, a hammock, and a Hawaii-themed fire pit, which is a nod to the family's former home state.
Former Phillies Pitcher Dickie Noles was among the special guests on hand for the surprise.
The Hoffman family is being supported by the Phillies community partner "Peter's Place" which provides grief counseling to families experiencing loss.
The custom swings were designed and built by King Swings, which is an Amish, family-owned company in Chester County.
