The Grimace Egg started as a meme blending the McDonald's mascot with Minecraft mob ideas.
There is no official Grimace Egg in vanilla Minecraft it’s purely fan content.
Some servers or modpacks have custom mobs or items that reference Grimace or fast food themes.
It went viral after TikToks and shorts showed Grimace spawning chaos in creative maps.
Players even made data packs that spawn a purple boss if you “hatch” a renamed dragon egg.
The egg has become a joke item in lore-themed SMPs and roleplay series.
There’s also Grimace Egg skins and resource packs that add themed gear or UI.
While not in the real game, Mojang developers joked about it on Twitter.
It’s a great example of community creativity turning memes into mini-canon.
