Here's something neat, guys.
A few playthroughs ago I learned something interesting. I'll try to tell what's going on based on trailers, the opening and some interesting levels with storytelling, I'll try to be the less fantiction-ish I can. Prepare yourselves, this is going to get deep:
Rayman Adventures happens during a war between the Lividstones and the Toads.... and the Toads are winning. Yeah, one would think that since the Dark Teensies hired them in Legends, they would be friends or something, but nope. There are some levels where the Toads actually help Rayman defeat the Lividstones, and of course, Rayman has to defeat the Toads after that. By connecting the points, I'm pretty sure the war is happening because of the huge value that the eggs from the Sacred Tree have. After all, as seen in the opening sequence the Lividstones stole them first, but in the first trailer it is shown how they were stupid enough to let some fall into other kingdoms. Minotaurs aren't involved in the war, they're just cleaning their stuff as usual. Toads and Lividstones don't even try to steal the eggs from them, since the Minotaurs are protected by the Gods of the Olympus Maximus. Finally, some Toads use the Dark Teensie's abandoned base as their secret place to make their plans. The entire Glade is in war, and as usual, the Teensies don't want to fight... and that turns them into the bad guys' punching bags.
Finally , as usual, Franckys are part of the Lividstone army, Ogers are part of the Toad army, and Giant Minotaurs are part of the Minotaur army.
