A plugin that can clean (remove) a world of any entity you'd like, not just mobs. Someone lags the server with minecarts? /clean minecart! Someone spams pig eggs? /clean pig!
This plugin is very simple, there's no config or anything, only one simple command.
Just type /clean, and it gives you a list of everything you can clean/remove. When you have decided what to clean, type /clean, followed by what you want cleaned. You can chain several entities together.
If you use the keyword "all", it cleans everything it can.
NOTE: This plugin relies on the entity list in Bukkit, so it doesn't need updating when there's a new entity added. It just works.
EXAMPLE:
/clean pig
/clean pig minecart zombie ghast experienceorb droppeditem painting
/clean all
