Google's blob emoji were a feature of its Android mobile operating system between 2013 and 2017. Google introduced the blobs as part of its Android KitKat mobile operating system in 2013. The next year, Google expanded the blob style to include the emojis that normally depict humans. As an example, instead of a flamenco dancer in Apple emoji style and its derivates, Google's blob style showed a less glamorous blob with a rose in its teeth. In 2016, Google redesigned the blobs into a gumdrop-shape. As Unicode, the group that establishes emoji standards, introduced skin tone and gender options to emojis, Google's emojis progressively appeared more as humans and less as yellow, amorphous blobs. Google retired the blobs in 2017 with the release of Android Oreo in favor of circular emojis similar in style to that of other platforms. Consistent cross-platform emoji interpretation was among the redesign's primary aims. The redesign, which had been in development for about a year, mimicked an Apple effort to include more detail in the emoji glyph and offer yellow skin tone as the default. Despite the their deprecation, Google's Gmail continued to use the blob emojis, as of 2021.
