It is a small, pink building that has a unique shape. It has fancy doors with a red carpet leading to it. The sign is in the shape of a scallop and reads the theater's name in purple letters alongside a marquee that shows what movie is playing as of the time.
The interior resembles an ordinary movie theater but the light fixtures are in the shape of a scallop just like the sign.
