What would be cool is if you could ride the Enderdragon just like the pig. Maybe be able to control it and shoot fire balls by left clicking. That would be pretty cool and to ride the Dragon you put a Saddle on it but its hard to get one on it.
In the future please use the formatted post style Found at: http://forums.bukkit.org/threads/example-plugin-request-formatting-formatted.46919/ also if you put more thought into your post it would help developers understand what it is exactly that you want to do. And finally, before you post on these forums search both the "Get plugins" area and "Bukkit Dev" I believe this plugin will do most of what you requested: http://dev.bukkit.org/server-mods/ridethadragon/
