I think it would be fun to have a item that would allow you to throw pranks at other players. An example could be a player could throw an egg at another player, and the other player would have to use their mouse to wipe it off.
I think we're going to be able to throw stuff at each other or send the requests like during the Halloween or Valentine's Day, where you can accept or deny and it sends them a prank items that either funny or mean. I also think that the staff is going to make it so we can't find eggs during the derp day stuff.
I'd honestly love it if the site implemented a sort of event where you could find really rare retired items all around the planets but as soon as you picked them up, they turned into something like "A Scria Sword? Don't you mean a Foam Sword?"
