The game stars popular cartoon character Bugs Bunny who finds and activates a time machine after taking a wrong turn at Albuquerque. He ends up in Nowhere, home of a sorcerer named Merlin Munroe ("Moyle" to Bugs). Merlin explains to Bugs that he is lost in time and that he must travel through different eras to collect clocks symbols and golden carrots that will allow him to return to the present. Players must help Bugs to go through five different eras of time to get back home. A sequel, Bugs Bunny and Taz: Time Busters was made for the same consoles.
