Rayman Jungle Run

These achievements are all related to collecting Lums throughout the game. Lums are the yellow bee-like creatures that you gather with Rayman by getting close to or touching them as you move through the level. There are 100 Lums to be collected in each level, and 45 levels in the game with Lums (the 5 bonus levels dont have any Lums). This means that there are actually 4500 total Lums up for grabs, but you only need to collect 3600 for the last of these achievements (or 80% of the total number of Lums in the game). However, you will need to collect each and every Lum (i.e. get a perfect on every level) to unlock some other achievements, so focus on that foremost. Each unique Lum will only be counted towards your total once, meaning you cannot just keep replaying the same level to work towards these achievements. Essentially, the game just sums your highest Lum total on each level for the count.

See "Fake Smile" for links to videos containing the locations of all the Lums.
