Dracula, Mavis, Johnny and the rest of the Drac Pack take a vacation on a luxury Monster Cruise Ship, where Dracula falls in love with the ship’s captain, Ericka, who’s secretly a descendant of Abraham Van Helsing, the notorious monster slayer.

When Van Helsing's mysterious invention, the "Monsterfication Ray," goes haywire, Drac and his monster pals are all transformed into humans, and Johnny becomes a monster. In their new mismatched bodies, Drac and Johnny must team up and race across the globe to find a cure before it's too late, and before they drive each other crazy.

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.

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.

Boog, Elliot, and their forest friends return with an all-new adventure, this time in a Big Top Circus! The comedy begins when Boog's pals choose their family obligations over the annual guy's trip, and a disappointed Boog decides to take a trip of his own, which leads him right into the middle of a circus ring...literally. When he switches places with a devious look-a-like circus grizzly and falls for an alluring Russian troupe member, he'll come to realize that maybe you don't have to choose between family and friendship after all.

The humans and animals believe a werewolf is on the loose, and former hunter Shaw uses the opportunity to re-open the season. Boog, Elliot, and Mr. Weenie have to face their fears and find the werewolf to get the season closed permanently.
