A happily domesticated grizzly bear named Boog, has his perfect world turned upside down after he meets Elliot, a scrawny, fast-talking one-horned wild mule deer. They both end up stranded together in the woods during hunting season and it's up to the duo to rally all the other forest animals and turn the tables on the hunters.
OPEN SEASON: SCARED SILLY opens with Elliot telling a campfire story about the legend of the Wailing Wampus Werewolf that lives in Timberline National Forest. Domesticated Boog is terrified by the story and decides to "chicken out" of their annual summer camping trip until he knows the werewolf is gone. Determined to help Boog overcome his fears, Elliot and their woodland friends band together to scare the fear out of Boog and uncover the mystery of the Wailing Wampus Werewolf.
