Minecraft wiki entry for Easter_eggs, associated text: Before the release of the Java Edition launcher version 2.1.497x, the launcher contained multiple Easter eggs. If the player hovered their cursor over the "Play" button for a few seconds, a random mob would appear in the bottom right corner of the launcher. In the top left corner of the launcher, the player could see a translucent creeper face. There was about a 1⁄11 chance of the creeper face being replaced with a shrugging emoticon, ¯\_(ツ)_/¯. When the player clicked on either of these, they turned solid white. Clicking them again would return them to their translucent state. In addition, if the player pressed ctrl+b, the experience orb pickup sound plays. These can no longer work because the launcher has since been updated.
