It creates a high amount of contrast and this heightens that mood of the sequence and the mood of the film. It has lots of establishing and medium shots which conveys the characters and the location. The characters in the costumes are different because it is an animated film. The viewer can see the monster form all the cartoony art work. These things depict the genre of the film which is a child's film this gives the audience a sense of a friendly, light hearted comedy film.
