After falling head over hooves in love with Giselle, Elliot's road to the altar takes a slight detour when Mr. Weenie is kidnapped by a group of pampered pets determined to return him to his owners. Elliott incessantly parades proudly with his antlers, until unwise rock-jumping sees them crushed, and thus his new pride. Bride Giselle thinks Elliott has commitment anxiety when he rushes off to take the lead in the rescue of canine buddy Mr. Weenie, who is kidnapped by a poodle's gang of master-devoted pets determined to reconvert him. The feral gang has great trouble even penetrating the heavily guarded holiday resort where the brainwashing attempt is happening.

Boog, a domesticated 900lb. Grizzly bear, finds himself stranded in the woods 3 days before Open Season. Forced to rely on Elliot, a fast-talking mule deer, the two form an unlikely friendship and must quickly rally other forest animals if they are to form a rag-tag army against the hunters. 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.
