The term 100% is used to describe the achievement of collecting every single Prize Bubble hidden within a level.

A good number of the Story Mode levels in both LittleBigPlanet 1 and LittleBigPlanet 2 contain areas that can only completed by multiple players, so it is encouraged that players work together to collect all the Prize Bubbles within a level.

Since LittleBigPlanet PSP lacks any multiplayer functionality, this is not an issue within the portable version of LittleBigPlanet because all the Prize Bubbles can be collected in a level by a single player.

If a player collected all of the prize bubbles throughout story mode, they would earn a golden trophy. In LittleBigPlanet 1, the trophy is "Booty Master", and in Little big Planet 2, it is called the "Uber Prize Collector" trophy. Trophies are also collected at the 25%, 50%, and 75% intervals in LittleBigPlanet 1, and at the 50% interval in LittleBigPlanet 2 also.

Benefits of 100%

Besides the obvious benefit of adding new content to your own personal Popit with each Prize Bubble collected, upon collecting every single Prize Bubble and achieving 100% within a level, the player will be awarded additional bonus items in the same manner as they are for initially completing a level and Acing a level.

It is only in Story Mode that you can be sure that achieving 100% in a level will unlock these items. When it comes to community levels, it is up to the Creator to decide whether or not he or she will award the player with tangible items for achieving 100% on their level. If a community level contains no prize bubbles, it is impossible to be awarded the "100%" icon on the level patch.
