There were three grizzly bears at Big Grizzly Mountain - Rocky, Mother Lode, and the cub, Nugget.
They were a family. A happy family.
Who liked causing a bit of trouble now and then. Changing the paths of the mine train. Messing with the prospectors on the mountain. And setting off just maybe a little bit of TNT.
Okay. A lot of TNT.
But it was fun. And they were just bears.
And Nugget was just a baby.
But the prospectors knew just what the bears knew.
That bears they may be, but they were doing it for their own entertainment.
Big Grizzly Mountain is basically Big Thunder Mountain, but with bears and the ride system of Expedition Everest - including the whole backwards bit.
