Rayman Origins

This achievement is for spending a total of 1 hour hovering/flying. You gain this ability in the second world. You use it by holding A again after jumping. You can let this rack up naturally over time or for those who wish to grind it with little or no effort, you can start up the "Wind Or Lose" stage in world 2. There are multiple vents that shoot continuous gusts of air straight up in the air. Jump into the gust and use hover, simply hold A and adjust your character so that it's stationary hovering. Now you can watch some TV while holding A :)

***Update***

Kennansoft has mentioned that he sticky taped his button down and left it for 2 hours, upon returning his achievement hadn't popped but did once he stopped hovering and started again. Just for any of you that might experience the same.

BUILT TO HURT has also mentioned that this popped for them after jumping off the Mosquito at the end of a flying stage so seemingly the time spent flying in these stages counts towards your total? If anyone else can confirm the same for sure that would be great.

On the basis that flying the mosquito counts, I've just found what I assume is a great place to get this without having to tape A down! After you have freed all the Nymphs, new levels unlock for all the old worlds. The second level you play in the jungle has a new level "Up and Down". Just before the end (the last section with the blue dudes who offer you their hands and let you swing on them) the hidden electoon level (top left) contains a mosquito element, and at the end you have to land your mosquito. Kill the dude firing rockets at the end, but not the normal enemy who just stands still. If you leave it in the air, top left and come back 1hr later, land it, the acheviement will pop just after. It popped for me when I exited the hidden level and completed the level.
