Google introduced the blobs, created by Japanese design studio IC4DESIGN, as part of its Android KitKat mobile operating system in 2013 as a way of redesigning the original emojis.
Google retired the blobs in 2017 with the release of Android Oreo in favor of circular emojis, designed by Jennifer Daniel, 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.
