I just picked up Littlebigplanet 2 and it's awesome.  I was looking through my trophies and realized that I'm only missing 2 trophies for the first game so before I get too far into the sequel, I want to finish off the first one for good.  One of these trophies though, is for collecting everything in the Pirates of the Caribean DLC and that requires three other people for those pesky four-person switches.  Another problem is that there is literally no one playing those levels online right now.  So if you have the pirates DLC for Littlebigplanet and want to collect everything in it, I'm looking for three other people to do just that.  My PSNID is I_NoScoped_Bambi so send me a message or an invite or just post here and once we get a total of four people, we can get this done.

Nobody, huh?  Well damn

I have not tried but i believe you can drag people into the DLC levels as the host even if they do not own it. Try joining a random level with a lot of people and see if they will help you out.
