Anyone willing to help me out searching for the 100% prize bubble trophy? Ideally I'll need 3 other players that are willing to do this and what levels do you need 2/3/4 players to get bubbles on? And I'm willing to help you guys out as well.

I mostly play it with my girlfriend so we only need 1 more

I'd be up for doing all the level which need 2 or more players to collect all the prize bubbles because I've hardly done any.

This is the best walkthrough I've found for the bubbles but it's a bit of a pain to use: Little Big Planet Game Guide - Page 3 - Game Guides at GameSpot
