길에서 태어나서 귀하게 자라란 뜻에서 샤를이라고 지었어. 달타냥의 동생이야. 고등어태비+하얀무늬 코에 하트가 거꾸로 박혀있어. 꼬리에는 열쇠가 걸려있어. 어릴 때 꼬리를 다쳐서 90도로 휘어졌거든

What Are Codex Pets?
Codex pets are virtual companions that live in your OpenAI Codex CLI terminal. Use /pet hatch to hatch a new pet, or install a custom pet package to personalize your coding companion. Custom Codex pets are defined by a pet.json file and a spritesheet.webp image — anyone can create and share one. Browse the gallery above to find community-made pets, copy the install command, and run it inside Codex to get your new companion.
