In March 2024, Punxsutawney Phil and Phyllis welcomed their baby groundhogs or kits. The following month, the Punxsutawney Groundhog Club shared that the kits were named Sunny and Shadow and were already growing and developing fur.

Punxsutawney Phil has become synonymous with Groundhog Day. The Pennsylvania tradition that started in the late 19th century has become one of the country's most well-known non-major holiday traditions.

Groundhog Day predictions about the coming of spring put the spotlight on Punxsutawney Phil every Feb. 2, but celebrating the midpoint between the shortest and darkest day of the year and the spring equinox has ancient roots in European agricultural life.
