Enemy aliens called "Woolies" intend to steal Earth's supply of yarnballs, and as Bubsy has the world's largest collection of yarnballs, he has the most at stake, and sets out to stop the Woolies and reclaim the yarnballs. The player must maneuver Bubsy through the levels, jumping on enemy "Woolies", and collecting stray yarn balls. The gameplay has been compared to the Sonic the Hedgehog games from the Sega Genesis era. (Wikipedia)
