This immutable v1.0.0 release uses the legacy v1-compatible 8×9 atlas and four-field manifest. Structural validation passed on 2026-07-26; it is not presented as the current newly-hatched v2 format. Runtime selection still depends on the user's product, account, workspace, and terminal. See the official Pets documentation and package contract .

Manual setup fallback

Prefer the ZIP? Install it manually

Use this fallback when npx is unavailable. ChatGPT Web can use the direct spritesheet when Upload pet is available for the account and workspace.

If your browser saved the ZIP elsewhere, replace the Downloads path before running the script. The script stops if the target pet already exists.
Open manual install assistant
Install, refresh, select

Use the pet without overwriting another install

The pinned installer verifies both files and stops if a different target folder exists. Manual files remain available as a fallback.

  1. 01
    Copy the one-line command

    Use the command at the top of this page. Its npm package version and pet ID are pinned.

  2. 02
    Run the verified installer

    The installer downloads pet.json and spritesheet.webp, checks their exact sizes and SHA-256 values, then writes both files together.

  3. 03
    Refresh and select

    In Desktop, open Settings > Pets > Refresh. In Codex CLI, use /pets or /pets penguin-astronaut-px05.

  4. 04
    Use the manual fallback if needed

    Download the ZIP or WebP below, compare it with the SHA-256 record, and preserve any matching folder before replacing it.
