What a find~ Didn't even know the series was getting a new season, but it's certainly nice getting an AP sequence from the series that has featured smooth animation and couple of transformations with well-detailed process.
Also, you can simply watch the episode here without having to live in France:

We just had to search by typing "Wakfu season 3 episode 3" in French translation, which is "Wakfu saison 3 episode 3".
Anyway, no further process, no process for the other girl, and no reversion process sadly. They just seem to get rescued out of the trap by some characters, and everything is suddenly back to normal like nothing happened.
