The Berenstain Bears Meet Bigpaw (1980)

Overview

It's Thanksgiving in Bear Country, and the Bear Family get nervous when Mama Bear thinks they've gotten a sign that the "Thanksgiving Legend of Bigpaw" is coming true. The legend says that when bears get greedy and don't share their harvest, Bigpaw will come to destroy Bear Country. Eventually, the bears all learn a lesson about who Bigpaw really is, and they celebrate the holiday.
