Does someone know this zombie mod?

Good afternoon to everyone, I need help to discover any mod that does what I'm looking for. Recently, me and my friends were planning to play Minecraft with a zombie mod. I've seen footage of it in Instagram about 2 months ago, it showed some guy mining and suddenly a horde of miner zombies spawned. I was looking for any mod that adds those zombies that can mine blocks, but I couldn't find. Can someone help me? Does someone knows any mod that adds these highly intelligent zombies?
