By building a ladder out of all his plungers to reach the window (and settling with an annoying bird who keeps defecating on him), Rayman manages to escape and free himself. Once liberated, he remembers the Globox kids and attempts to return through one of the Rabbid holes to rescue them, but winds up getting stuck in the hole. In a post-credits scene, Rayman is still stuck in the hole through the night, and sheep come to eat the leftovers of his picnic. The game began development in the Ubisoft Montpellier studio. The studio head Michel Ancel sketched an initial concept for a rabbit character, and from there, the idea of a mass invasion of bunnies grew. The team then began work on a traditional action game platformer, then tentatively titled "Rayman 4". However, upon receiving development kits from Nintendo, the team began focusing on implementing a wide range of gameplay types. Another project called Rayman 4 was in development for next-generation consoles, with Michel Ancel being involved, unlike Rayman 3 where he was just a creative advisor. The game would have released on PS3, Xbox 360, Wii, and PC, but was cancelled by E3 2006 in favour of the Raving Rabbids spinoff series. When it became clear that these were not going to fit into a traditional platformer game, Rayman Raving Rabbids was altered to become a game consisting of separated trials. The changes meant that some of the trials and concepts revealed before the game's release did not appear in the final game, such as hawk and tarantula riding. While Ancel was seen as one of the main figures behind the project before E3, he left the project after the revamp, and is only credited with character design in the final game. The PC version is made in Ubisoft's studio in Sofia. "Rayman Raving Rabbids" is also available for the Xbox 360, PlayStation 2, Wii, Game Boy Advance, PC, and Nintendo DS. The game has received positive reviews. "IGN" and "GameSpot" complimented the game's "sick sense of humor" and a heavy emphasis on fun, as well as the design of the bunnies and the game in general. Reviews highlighted the story, music and sound, and said that gameplay is addictive and optimized for the Wii. A few critics claimed that other developers of Wii launch titles had simply ported their games and "tacked on" Wii controls. It is currently one of the highest-selling third party games for the Wii.
