  showAnyCustomNames: true
  //Whether or not to display the name of the setup for each megacreep as if it was a player name.
  //This flag only counts for mobs that are spawned in a world that megacreeps is not active for.

  activeworlds:
  //The worlds where the replacement of spawning mobs is wanted.

  - world

  additionalTypes:
  //You can spawn all types that you added for replacing normally spawning mobs.
  //This list is just for adding those you want to spawn by command WITHOUT adding them to the replacement pool.
  //In this example, the types would not be needed, since they are already added to natural spawns. This is showcase only.

    removeNonreplaceableMobs: false
    //Do you want to remove all spawning mobs that you don't have a setup for?
    //Care: If you put this to true and are missing setups for a level, you will never know, but have less mobs spawning!
    //Care: If you have no setups for e.g. slimes, there won't be any slimes spawning anymore.

    hpDisplayType: none
    //What kind of display type for mob's hitpoints you want to use. Accepts numbers (1, 2 and 3 as of now).

      level1: 60
      level2: 30
      level3: 10
      //The chances are relative! They spawn in a relation of 60/30/10 for level 1/2/3.
      //This means, if you spawn 10 mobs, 6 would be level1, 3 level2 and 1 level3. You could also make this 6/3/1 in this example.
      //If you prefer percentages, make sure that summing up all level chances results in 100.
      //You are free to add or remove levels if you want, as long as they are spelled correctly.

    //The types that are used to replace normal mobs for this world. Feel free to add your own or modify the existing ones.
