To fill the space with more levity, the signs became illustrated graphics within the environment. Animal friendships became theme of these illustrations became focused to highlight the beautiful relationships of very different animals within the real world. The theme also helps draw parallels between the positive relationships between the patients, parents, and staff.
Meta depictions of medical practices or devices were avoided to avoid reinforcing the idea the hospital just provides medical care and not tend to the mental needs of its patients. Animals are depicted with a vector like style using texture to emphasis dimension. Each sign contains two different animal friends for each floor with a small story-like excerpt for the audience to enjoy reading. Each floor keeps a consistent color palette for its typographic information and depictions of its animals.
Each sign has the animal friends each doing something different to create landmarks from the signage. Larger murals are used at elevator hubs or major hospital sections like the cafeteria. Background elements of each floor's sign are drawn from the environment these animals inhabit. Such as in Floor 1 with the Elephant and Egret, the background is created to show the plains of Africa where they coexist.
