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, Mr. Weenie and their woodland friends band together to scare the fear out of Boog and uncover the mystery of the Wailing Wampus Werewolf.
Also, Shaw, now a tour guide, witnesses an unseen creature in the forest and begs Gordy to allow open season and Shaw is determined to hunt down Boog and Elliot and catch the werewolf. To do so, he recruits his old friends Ed and Edna. Meanwhile, Elliot is heartbroken and catches the werewolf by himself alone after Boog angrily breaks up with him. A starving Mr. Weenie believes he is the werewolf. At Dead Bear Gulch, Elliot and Mr. Weenie are both caught by the werewolf with it reveals Shaw inside, but Boog and his friends leaped to the rescue. Shaw is defeated (in which he is revealed to be allergic to hornets) and arrested for impersonating a monster and creating a general panic, and open season is permanently shut down.
In the end the werewolf turns out to be real, but Elliot befriends him by dancing with him as he joins their camp out.
The next morning, Bobbie and Bob return to the R.V. and Bobbie tells Mr. Weenie that today is his birthday. Mr. Weenie says to the audience, "And so everybody did live happily ever after, including Mr. Weenie. The End".
Before the credits roll, the werewolf wants Boog to become a werewolf lady one more time, but Boog refuses.
