Rayman and his friends getting roped by the Magician into dancing with him in the last stage of Origins isn't so odd when you recall that the first Rayman game had our limbless wonder dance with while apparently befriending most of the bosses after beating them. The dance scene might be that the Magician tricked Rayman and Co. into thinking they were friends.
In Origins' water world, the Sea of Serendipity, several levels are incredibly dark and require you to stay in the light to avoid dying. In Legends' water world, 20,000 Lums Under the Sea, several levels are incredibly dark and require you to stayoutof the light to avoid dying.
Rayman needing to get a power-up in order to punch and hang in the first game might seem like You Have Researched Breathing to some, but keep in mind Rayman doesn't have arms. His hands aren't even attached to his body. So punching and hanging probably works differently for him.

The 'Wanna Kick Rayman?' shorts for Rayman 3 are full of this. Assuming the footage is canon, Andre had his henchmen round up helpless animals, rip off their fur (if any), dress them up as Rayman and kill them in various ways for amusement. Some of them are rather cruel too. One involves frying a slug from the inside using a battery that's inserted through the back end.
Most of the other ones are a little more family friendly, with more slapstick style deaths. With the exception of 273, where one of the creatures gets beaten to death with a hammer, causing one of his eyes to shoot out of its socket and hit the camera lens.
Don't forget the bit at the beginning of each clip: 'A collection of 547 lessons on VHS and DVD' of these experiments, one lesson per tape or disc. Considering that each episode lasts less than a minute, and considering a DVD can fit about 3 hours of footage...
The Land of the Livid Dead is relatively neat. It's also pretty hilarious, considering it's full of grannies and the such. So the Land of the Livid Dead is an afterlife, right? So there brings the question: Why do the grannies also seem to be some of the most humanlike characters?
