Annie is an independent girl who has transformed into a larger, friendly monster with light blue skin, sharp teeth, and clawed fingers after drinking a bubbly liquid. She sports a black v-neck t-shirt, red long pants, black shoes with white soles, and long red fingerless gloves, although the ends of her gloves are torn. Her signature black beanie, adorned with cat-like ears, completes her look. Despite her monstrous appearance, she radiates friendliness as she sings along with her boyfriend to the song 'Animal.'
