Coding theme at a glance
The dark chest badge and green terminal prompt stay centered in the standing poses, so Pixelcorn reads as a coding companion rather than a generic rainbow mascot.
Codex pet package
Pixelcorn combines a white chibi unicorn, rainbow mane and tail, gold horn, and a green terminal badge in one high-contrast desktop companion. Its standing poses keep the coding theme visible, while the movement rows switch to a readable side profile before you download the package.

Pet profile
Use these visible package traits to decide whether this pet fits your desktop before you install it.
The dark chest badge and green terminal prompt stay centered in the standing poses, so Pixelcorn reads as a coding companion rather than a generic rainbow mascot.
A white body and dark hooves frame the rainbow mane and tail. The color is concentrated around the silhouette instead of filling the whole sprite cell.
Idle, waving, waiting, and review use a front-facing body, while the running rows turn Pixelcorn sideways and let the tail carry most of the motion.
Animation review
These observations come from the original package spritesheet, not a generic species description.
Run-left and run-right frames stretch the body into a side profile without losing the horn, rainbow tail, or terminal badge. This makes direction changes easy to recognize at desktop scale.
The wave raises one dark hoof beside the face. Jump frames lift both forelegs and compress the lower body, creating a stronger vertical change than the idle loop.
Failed frames lower the head and close the eyes, waiting settles into a calmer seated posture, and review returns to an upright pose with a more concentrated expression.
