Tilly the Calico Cat

Tilly is a detailed long-haired calico cat with orange, black, and white markings, a full chest ruff, green-yellow eyes, and a raised fluffy tail. The atlas moves between composed seated portraits, low running poses, a paw-up wave, and visibly subdued failure frames.

Pet profile

What makes Tilly distinct?

Use these visible package traits to decide whether this pet fits your desktop before you install it.

Detailed calico markings

The orange forehead blaze, dark face patches, white muzzle, and full white chest remain consistent across front-facing and side-facing frames.

Readable feline movement

Running frames lower and lengthen the body while the tail stays high, separating locomotion from Tilly's upright idle and review poses.

Soft desktop presence

Rounded fur edges and mostly natural coat colors give Tilly a quieter visual profile than the catalog's pixel mascots and fantasy creatures.

Animation review

How Tilly's states read

These observations come from the original package spritesheet, not a generic species description.

Idle and waiting

Idle frames use small eye and head changes around a stable seated silhouette. Waiting lowers the body and softens the expression without changing the recognizable calico face pattern.

Running and jumping

The running rows use a side profile with stretched forelegs and a raised tail. Jumping returns to a front view and lifts one paw, so the action does not look like another run frame.

Failed and review

Failed frames move from a worried sit into a curled, head-down posture. Review restores the upright body and uses smaller face and paw changes for a focused look.
