Black Bear Invasion

The wild adventures continue in northern Maine, where Casey Anderson finds himself in the den of a wild black bear family! On a research expedition to study the species, the team's GPS malfunctions and Casey stumbles upon the bear den, literally bringing viewers up-close and personal to the dangerous black bears. Continuing his quest, Casey also meets an orphaned six-week old cub, dubbed 'Casey Junior,' and teaches the youngster how to walk, swim, climb, and raid a beehive.
