Bunnies are a type of mob created by Ryan Holtz. He initially stated he only made them for fun and that they might not be added to vanilla Minecraft, but he later stated they they will be added but "[he] just needs to get off [his] lazy butt and finish them..."

On June 7 2014, when asked, Ryan Holtz stated during a livestream on Twitch of himself playing Mega Man, that bunnies were "most probably coming in 1.8", however, the livestream isn't available for viewing.
