Norby and Yobo's Great Adventure

Whenever Admiral Yobo summoned Jeff and Norby, it usually meant they were in trouble. This time, the Martian office has a mission for them: a wild-safari photo shoot...in Earth's distant past.

Thanks to Norby's hyperspace skills, the journey is a success. But it's a jungle out there — the elephants are stampeding, the natives are restless...and Norby's lost the trail that can take them back home!
