Eggrobo and Mecha Sonic have delivered a chain letter to Knuckles. It contained the following message: "Send this letter to ten friends of yours, otherwise you'll be paralised and won't be able to walk left or right". Since Knuckles doesn't have this much friends, he (in his desire to restore his normal walking abilities) goes on an adventure to kick their robotic butts.

Bubsy is a series of video games created by Michael Berlyn and developed and published by Accolade.[1] Four games were released in the series: Bubsy in Claws Encounters of the Furred Kind, Bubsy 2, Bubsy in Fractured Furry Tales and Bubsy 3D. The games were platform games similar to Super Mario Bros. and Sonic the Hedgehog. The games were released for the SNES, Mega Drive/Genesis, Atari Jaguar, the PC and PlayStation in the early and mid-1990s.

Bugs Bunny in Double Trouble is a video game developed by Atod AB for the Sega Genesis and Game Gear, released in 1996. The game stars Bugs Bunny and features pre-rendered 3D graphics (similar to Donkey Kong Country for the Super Nintendo) Similarly to 1994's Mickey Mania: The Timeless Adventures of Mickey Mouse, the levels in this game are mainly based on individual Bugs Bunny cartoons from Warner Bros.' Looney Tunes and Merrie Melodies series, stringing them together by having Bugs trapped in a "Televisor" created by Yosemite Sam as a mad scientist. Seven of the levels are based on the Bugs Bunny cartoons Duck! Rabbit, Duck!, Bully for Bugs, Knighty Knight Bugs, Hare-Abian Nights, Spaced Out Bunny, Mad as a Mars Hare, and Hare-Way to the Stars, while the other level, entitled Haunted Hare, is based on elements of Bewitched Bunny and Hair-Raising Hare. Each level features objectives, designs, and opposing characters based on the source cartoon(s), though some levels take liberties to include plot elements, weapons, and obstacles that weren't present in the original cartoons. For example, the Hare-Abian Nights level features a duel with Yosemite Sam over a genie's lamp, and Spaced Out Bunny is essentially a race against Marvin the Martian to Mars. As well, the Duck! Rabbit, Duck! level does not have the snow present in the original cartoon, giving it a design closer to Chuck Jones' earlier "hunting trilogy" cartoons, like Rabbit Fire.
