On April 5, 2006, Ubisoft announced Ancel was leading the development of the fourth game in the "Rayman" series, "Rayman Raving Rabbids", for Wii. The game began production in early 2005 and was released on November 15, 2006 for the launch of the Wii. However, Ancel was absent from the project after its E3 announcement, and he has made no public appearances regarding the game after the development team switched focus from a free-roaming platformer to the final minigames format shortly after E3. In the final game Ancel was credited with storyboarding and character design, while design credits were shared between other people.
