Plugin MobAge

MobAge, automatic cleanup for inactive mobs

MobAge is a legacy Bukkit plugin for a Minecraft server that gives animals and monsters an age counter. Mobs that receive no interaction gradually grow older and are removed after the configured limit, helping clear stray creatures that would otherwise remain loaded and contribute to clutter or lag.

Administrators can define the age limit, checking interval, mob limit, and active radius. Spawns are restricted around online players, while players, tamed mobs, and Ender Dragons remain protected. Movement nearby, damage, targeting, taming, or interaction resets a mob’s age. Our BoxToPlay team recommends it mainly as a historical server management tool, since its listed support targets early CraftBukkit releases.
