The texture of the warm piglet — pig_warm_baby.png — contains pixels resembling the warm pig's texture in an unmapped area. This is unexpected as it unnecessarily increases the stored image data and thus the file size, can lead to slight confusion among resource pack authors regarding the proper UV mapping, and is inconsistent with the other piglets' textures, which do not contain these pixels.
Attached to this report are the current textures of all piglets, an image highlighting the affected pixels, and a revision of the texture with those pixels removed.
