Animaniacs: Hollywood Hypnotics is a cancelled 2D platformer based on the television series Animaniacs. The game was developed by Full Fat Games and was planned to be published by SWING Entertainment. A prototype has been found and released by Hidden Palace. In the game, Pinky and The Brain set up hidden speakers that induct mind control through eerie sounds to people and make them believe they are always shooting movies, so Brain can turn the Warner Bros. Water Tower into a rocket that would launch a satellite into space that plays loud barking noises to disrupt people of the planet. Yakko, Wakko and Dot, the only three immune to the eerie sounds set off to destroy the hidden speakers.

Panel de Pon GB is a canceled game for the Game Boy Color. The game was mostly a port of Panel de Pon (SFC), but with a new story and some elements from the cancelled Panel de Pon 64, which later resurfaced via the Nintendo Puzzle Collection compilation for the Gamecube. The game was eventually cancelled and turned into Pokémon de PanePon. However, most of the game data still remains inside of the Pokémon de PanePon rom.

Sound Fantasy, titled Sound Factory during development, is an unreleased video game for the Super NES/Super Famicom. Designer Toshio Iwai was inspired by his earlier interactive installation art piece titled Music Insects, to develop a video game at Nintendo between 1993 and late 1994. The completed product was inexplicably canceled by Nintendo, and the game's key elements were later developed into Maxis's 1996 PC game release titled SimTunes. Sound Fantasy contains eccentric concepts and untested game mechanics. Music games, especially on home consoles, were not popular in the early 1990s, and it wouldn't be until much later in the decade that they gained mainstream attention. The Sound Fantasy prototype contains four different games in one cartridge. Pix Quartet was inspired by Toshio Iwai's Music Insects. There are four insects of different colors, where the player can select different insect to each represent a different instrument. They crawl all over the screen, where the player can draw. Insects that crawl over a colored pixel make a note. Each color represents a different note for each insects. Sample Demos can be loaded to demonstrate the capabilities of this game. Beat Hopper contains three different modes: A-type, B-type and Training. A-type is a rhythm game in the style of Q-bert, where an insect on a pogo must make every block disappear after stepping on it as many times needed. Each block makes its own sound and the order does not matter. The player can improvise a song with each block. B-type requires the player to follow a path of blocks that appears every time the player touches one. The player must make as many steps as possible without losing three lives. Ice Sweeper indicates two modes: A-type and B-type. This game is a Breakout clone with a few new twists added after a few stages, such as four bats controlled by a single player. Star Fly is inspired by music boxes, where the player can set a sequence of stars in the sky, to compose a song. A higher star corresponds to a higher musical note. The player may set the speed and the tone.

Twelve Tales: Conker 64 (known in the PAL regions as Twelve Tales Conker) is a cancelled video game that was going to be released for the Nintendo 64. First announced as Conker's Quest at E3 1997, the game would have followed the all ages environment of Conker's Pocket Tales, a handheld title released during its prolonged development cycle. Before the game could be finished, Rare had already made similar games that had already achieved general acclaim, most notably Banjo-Kazooie and Diddy Kong Racing. The developers began to receive criticism for creating another innocent platformer starring cute and friendly animals. In 1999, Rareware revealed that they were going to entirely redesign the game to appeal to an older audience. While it was first believed to be an April Fool's joke, the game went unreleased and replaced with Conker's Bad Fur Day in 2001.
