The "Frozen"-themed party also featured an ice sculpture in the shape of a snowflake that would have left Queen Elsa impressed. The message on the sculpture: "HAPPY BIRTHDAY BLUE."

The party for their little minion comes as Jay Z and Beyonce have cooled down lately -- literally! In addition to the "Frozen" party, they recently took an vacation to Iceland, where Beyonce posted multiple stunning photos on her Instagram.
