Darknuju's fun plugin

Introduction:

Hello my name is darknuju and I am a new plugin developer and this is my first published plugin. This plugin is designed and created for one purpose, to make goofing around on servers with friends fun by adding stuff like explosions, sparkles, and rides.

Commands:

/blowup [player/block]: Blows up you another player or stops other people from blowing you up.
/sparkle [color]: Toggles sparkle or changes the color.
/head: Puts whatever item/block in your hand on your head.
/ride <player>: Allows you to ride another player.
/sudosay <player> <args>: Allows you to speak for another player.

Permissions:

/blowup: Fun.blowup
/sparkle: Fun.sparkle
/head: Fun.head
/ride: Fun.ride
/sudosay: Fun.say


What should I add next to make it more fun?
(Should work fine in 1.6.2+)
