Codex pet package
This penguin chick pairs a soft gray body with a black cap, white cheek patches and tiny dark feet. Choose it for a natural animal theme and a clear side-facing waddle. Its quieter front-facing states rely on small head and eye changes, so they are less distinct at a glance. We inspected the original atlas and site preview; desktop installation was not tested.

Pet profile
Use these visible package traits to decide whether this pet fits your desktop before you install it.
The white cheek patches against the black head remain the strongest visual cue in a small preview. Fine downy texture and individual toes fade sooner. This suits readers who want a recognizable animal without clothing, a laptop or floating status symbols.
Run-left and run-right turn the chick fully sideways, alternating its short feet and flippers. Those side profiles are easier to tell apart than front-facing movement loops. The separate Running row also uses a side-facing stepping sequence, keeping active movement distinct from the standing poses.
The dark outline separates the chick from a pale background, while its gray body and white face stand out on a dark one. The black cap and tiny feet are less distinct against darkness. Transparent space around the original artwork lets your chosen background affect the result.
Animation review
These observations come from the original package spritesheet, not a generic species description.
Wave raises one flipper beside the body. Jump first squashes the chick, then lifts it with both feet visible before landing. These larger silhouette changes are easier to spot than the small blink in idle.
The chick lowers its head, closes its eyes and folds forward until its face rests near the ground. That low, wide final pose clearly differs from standing. Check it in the preview if you prefer a subtle failure cue over a whole-body collapse.
Waiting stays front-facing with small head turns and tilts instead of a side-facing waddle. Review also uses head tilts, blinks and narrowed eyes, without a magnifying glass or code panel. Choose a companion with larger props if immediate waiting-versus-review recognition matters most.
