Grumm[3]

Erik 'Grum' Broes was a software engineer at Mojang Studios. He was originally hired to develop the official modding API and maintain the Minecraft server. In August 2012, his duties were broadened, to include general game development. At some point from June 2024 to June 2025 , he left Mojang.

Broes has been actively involved with the Minecraft community, and has joined with many prominent Minecraft figures, such as appearing in SethBling's channel on YouTube,[4] a popular and well-known channel regarding Minecraft.

Broes was also previously an admin on the Dutch TweakCraft server.[5][6] While not active in-game, he was mostly active on the server's IRC channel and mainly worked on the server's plugins and coding.

Trivia

  • Grumm, in-game, has been hidden in most of the "cover pictures" of snapshots starting with Java Edition 13w19a.
  • Starting in Minecraft 1.6, most mobs named "Grumm" or "Dinnerbone" (or the players themselves) are rendered upside-down.
