The Ore Creeper mod by Cozary adds new Creeper variants based on vanilla ores. While exploring the world, players can encounter these special Creepers that look like the ore they represent. When they explode, they do not cause damage like regular Creepers. Instead, the blocks around them are transformed into ores that match the Creeper type.
This makes them a useful tool for gathering resources rather than a threat. Killing an Ore Creeper also drops some loot. The mod includes a config file that allows players to adjust the spawn rate and explosion size to fit their gameplay preferences. In addition to the Creeper variants, there is a TNT version that can turn a regular Creeper into an Ore Creeper. For players using other mods such as EnderIO, it is possible to capture an Ore Creeper with a Soul Vial and use it in a spawner to create a renewable ore farm. The mod is available for Forge, Neoforge and Fabric.
