Amy, a white dog with an orange nose, pink bows in her hair, and a pink dress, lives in the Berry Household as Eric's sister. Alongside Eric and their friend Harry, Amy learns educational concepts and life skills from Hello Kitty and Mimmy. These lessons cover mastering practical skills like telling time, understanding weights, identifying shapes, and exploring sounds. She engages in activities such as playing with origami, discovering objects that stick together, and interacting with different sounds and musical instruments. Amy also focuses on social and behavioral growth, including cleaning up toys, resolving conflicts with friends, respectfully lending and borrowing items, assisting others, and following rules at friends' houses. Daily routines, like preparing for bedtime by putting on pajamas and brushing teeth, are part of her learning. Information about Amy exists only within "Hello Kitty & Friends: Let's Learn Together".
