Name Some *FUN* Bukkit Plugins Here!

Alright, so we got our base essentials plugins to keep our server running very well, my question is, can you recommend a fun plugin that you've tryed yourself that you or your server players have enjoyed!?

I recommend magicspells (Can shoot fireballs, make people drunk, tons of stuff), Rider (Let's you ride on players shoulders! Really fun), Heads (lets you get the head of a player in-game and you could wear them too lol) and disguisecraft (disguise as everyone and everything). Have fun lol
