Minecraft has had multiple mobs fail to reach the main game, and with the recent changes to content drops with the Spring to Life update, these mobs should return soon. Starting in 2017, Minecraft offered players the option to vote for mobs and occasional biomes with new mobs to join the game. However, this vote soon proved to be controversial, as good options were left on the back burner, even though there were reassurances that they could come back. Luckily, this yearly vote has been scrapped.
