Codex pet package
Mosaic Invader turns a cyan, big-eyed character into a grid of small square tiles. Its antennae and block-shaped arms make a clear arcade-style outline. The texture is easiest to appreciate enlarged; at smaller sizes the large eyes and broad failure pose carry more meaning than individual tiles.

Pet profile
Use these visible package traits to decide whether this pet fits your desktop before you install it.
Both the body and antenna tips use visible cyan squares with darker seams. This gives it a more rigid, graphic appearance than Axobotl's rounded body and frills. At reduced scale the seams merge, leaving a simpler blue shape with white eyes.
The feet shift and spread differently in the two travel directions, but the character remains largely front-facing. Direction is less immediate than Eagle's fully turned beak and body. Running also keeps the eyes forward while alternating the angular legs.
White eye panels and the cyan body retain contrast on the tested dark surface. The black outer border is easier to follow on a pale one. Choose it for a bright graphic companion, rather than for natural animal anatomy or soft shading.
Animation review
These observations come from the original package spritesheet, not a generic species description.
Wave lifts an arm beside the head. Jump starts with a low, wide body, lifts the square feet and antennae, then returns to the compressed shape. Looking across the sequence avoids mistaking its preparation frame for the entire jump.
The eye panels narrow, white tear streaks appear and the antennae bend inward. The final frame is markedly lower and wider. That outline change is a stronger small-size signal than the individual tear pixels.
Waiting retains a relaxed front-facing outline with closed-eye and leaning frames. Review tilts the tiled body and changes the arm and eye positions. No document or magnifying glass is added, so these two states need closer inspection than failure or waving.
Compare before installing
Compare the same broad cyan color family with pink frills, a curved tail and more facial gestures.
Compare a much simpler floating face if the tiled texture and moving antennae feel too busy.

How to use
Scan the 9-state preview grid to confirm the spritesheet covers idle, movement, waving, failed, waiting, and review states.
Download the package zip, or save spritesheet.webp and pet.json into a folder named after this pet id.
Copy both files into ~/.codex/pets/<pet-id>/ so Codex can discover the custom pet package.
Use /pet inside Codex, or open Settings -> Appearance -> Pets and choose this installed pet. Refresh custom pets if it is not listed yet.
