From the back of the game cassette box:
For a bear that's smarter than the average, life in Jellystone Park should be one long picnic. After all, everyone knows picnics mean picnic baskets! But life has taken a nasty turn. Poor little lovable Boo Boo has been "bearnapped" by a bloodthirsty hunter and is a prisoner somewhere in the Park!
Heroic as ever, Yogi is on Boo Boo's trail. But Jellystone's a big place and you'll have to find plenty of tasty snacks to keep our trusty bear's strength up. Especially since along the way Yogi's pursued by angry campers, a furious Ranger, ferocious animals and homicidal hunters! Time's getting short too. Yogi's hibernation season is nearly here. So you'll need speed and a lot of bare (ouch!) cunning to rescue Boo Boo before Yogi slumps into his slumbers.
Step into Yogi's paws and see how long you can survive in this bonanza of fast-moving arcade action!
