- This keychain was created to commemorate the release of the scrubs, which were born from a project that utilized Asahiyama Zoo's support product initiatives. It was selected because of its affinity with medical facilities, where people also attach it to their belongings.
- Artists from the NPO Wonder Art, which originated from hospital art, drew on the "will to live" of animals for this occasion. Six pieces were selected from a total of six artists, including the pieces used on the scrubs. The back of the keychain can be written with a permanent marker.
- Silhouette design
- An acrylic keychain consisting of two parts: the artwork and the logo
