Rayman Origins glitch: The Bubble Bug - Fly everywhere, pass through walls, go out of bounds & more. 

This is what I call The Bubble Bug, check bellow for a complete description and more informations.
What we can do includes flying almost everywhere, passing through walls and going out of bounds where the camera not lock that.
Set up is rather simple we need at least two characters, this may be the reason because it was not discovered sooner, it involve co-op.
With two players Player 2 is standing on Player 1 with legs arms maintained up and then press the bubblize button to autokill then player 1 deposit the bubble and can jump on it, on the right side. with this method we can set-up three bubbles that we can ride.
Another method with three players is to stack three character, with player that will ride the bubble on top, this as the advantage to directly ride the bubble, as with the first method if we didn't jump in the right place it may revive the bubble.
I recommend to bubblize Globox, because with other characters we are too close to the bubble and it will be repelled from the player causing it to constantly go backward, and going forward slower.
The bug may work on all console having a kill button, I tested this on PC and Wii (emulator)
It will not work on Moskito levels because the camera is locked to a part of the level until we ride Moskito.
We can pass through walls while punching, roll attack and even ground pound, underwater you don't have to attack to pass through walls
Some damaging obstacles will still cause damages, some will not
It is possible to go out of bound in some secret places, like hidden cages or skulls coin.
Here is a non-exhaustive list of places where this is possible :
Climb Out
Savage Swarms
Crazy Bouncing
Wind or Lose
Piping Hot!
Fickle fruit
Port o Panic
Mystical Munkeys
On Top of Old Smokey
Mecha No Mistake! (small)
Murray of the Deep
Rayman Legends have some traces of the bug ( • The bubble bug is not ... ), but we instantly fall if we try to ride the bubble. Even if it can work, it won't work in challenge as bubblized characters are not allowed to prevent continuous reviving of players.
What a funny discovery, it's not every day you find something like that. :)
