As of my knowledge in January 2022, there has not been an official Minecraft update specifically focused on SCP (Secure, Contain, Protect) creatures or a SCP-themed zoo. However, Minecraft is a highly moddable game, and there are several mods available that introduce SCP-related content. One of the most popular SCP mods for Minecraft is "SCP: Lockdown," which adds various SCP entities, items, and locations to the game. This mod allows players to encounter and interact with SCPs within their Minecraft world. While there may not be an official Minecraft update centered around SCP creatures or a zoo, the modding community offers various options for players interested in incorporating SCP content into their Minecraft experience. It's always a good idea to check for the latest mods and updates on Minecraft modding websites or forums to see if there have been any recent developments in this area.
