Move It! Shake It! MousekeDance It! Street Party is a lot of fun, and it is a great way to celebrate Mickey and Minnie’s birthdays. It takes place at least twice a day during Mickey & Minnie’s Surprise Celebration. If you want great pictures of the world’s most famous mice, stand on the inside loop in front of Cinderella Castle. If you’re on the outside loop, closer to the castle, you’ll get lots of pictures of the backs of their heads.
