The sunny kingdom of Arendale has finally ushered in Anna's birthday (voiced by Christine Bell Kristen Bell). Aisha (voiced by Idina Menzel Idina Menzel) and Christopher (Jonathan Grove Jonathan Groff) and Xuebao (Josh Gad Josh Gad) carefully prepared this birthday celebration a few weeks ago, and our dedicated queen will not allow the slightest mistake. When she confirmed that everything was ready, she arranged for the two partners to watch the meeting hall to prevent the cake from being damaged, and she went into the castle alone to wake Anna in her sleep. The memories of the two sisters' birthdays can be traced back to the years when Aisha was locked up in her room, so Aisha attached great importance to this special day. She carefully selected all kinds of small gifts for Anna, but maybe she worked so hard in the past few weeks that she caught a cold. Aisha sneezed repeatedly along the way, and many little Xuebao were born from the sneeze, causing a lot of trouble to Christopher and Xuebao.
