A medieval curse gives Brother and Sister Bear an adventure they'll never forget!   On a beautiful sunny day in Bear Country Park, Brother Bear is riding his skateboard and Sister Bear and her new butterfly friend are skipping rope. Then they notice a sign on the Shagbark Hickory Bulletin Board: HELP WANTED! AT ARCHEOLOGICAL DIGS. Determined to be the first to apply, Sister and Brother Bear hotpaw it to the Bearsonian Institution and meet Professor Actual Factual. He drives them to the dig, where Sister Bear unearths a medieval suit of armor, complete with a curse. They transport the find back to the museum and assemble the knight, hoping it will attract bears from all over. But the next morning, it comes charging out of the tower room! Will the exhibit go on and give everyone in Bear Country a true knight to remember?
