Harper presented the Phils' mascot with a wrapped present prior to the start of Sunday's game at Citizens Bank Park.
Inside the box was a pair of new Phanatic shoes - replicas of the green cleats Harper wore on Opening Day!
The Phanatic gave Harper a hug as the friendship between the two continues to grow.
The Phillies also gave the Phanatic another gift: a 5-1 win over the Miami Marlins.
While the Phanatic's actual birthday is April 25, the Phillies celebrated it on Sunday. Hey, the Phanatic deserves two birthdays, doesn't he?
