The Wii had a cancelled game where you stuffed a Wiimote into a plush toy

Wii game where players would need to put their controller into an exclusive plush toy. Called WiiWaa, the title was being developed by Zoink Games for the Wii in the late 2000s, although a number of factors meant it never saw an official release.A video published yesterday (June 19) by DidYouKnowGaming dives into the game’s history, with Zoink Games president Klaus Lyngeled providing more information about the plush-type game.Lyngeled told DidYouKnowGaming that the idea for WiiWaa came from when he would play games with his son, as after they’d finished on the console together, his son would go off and continue playing the game with his toys, using his imagination to keep the characters alive.“Then I was realising “wow that’s kinda cool, that’s how you would actually animate the character in the game [emulating the movement of a child playing with it] with a controller.” [So I thought] what if I put the Wiimote inside one of his plush toys, you know?”You can see the plush prototype in action here.Development then began in early 2008, with a prototype plush toy and a game demo being worked on.

WiiWaa was set to be an adventure game, with the protagonist exploring and completing smaller puzzles. After putting the Wiimote in the plush via its mouth, the player would need to “waddle” the character down fixed pathways.The plush’s springy ears could have been used to measure the height of the character’s in-game bounce, with readings from how far the Wiimote moved representing the height of the bounce during play.During development though WiiWaa struggled to get past Nintendo, as it had strict controller add-on rules for the Wii.
