When some new grizzly bears arrive at the park during a hot summer, it's up to Andy to make sure they have everything they need to help them get rid of their winter coats. But Andy doesn't know what they might need to help them to do just that. To find the answer, he jets off in his safari-mobile, heading to North America in search of some grizzlies. After meeting some bison and a marmot, the bears lead Andy to a forest where he discovers the answer to the question. The bears use the rough bark of the trees to shed their winter coats. Amazing!
