Plot
California's annual giant vegetable competition is approaching with the coveted Golden Carrot as its prize. Oh and Russell provide a humane pest control business, "Anti-Pesto", protecting the townspeople's vegetables. One morning, Oh devises a plan to lose weight and creates the Mind Manipulation-O-Matic to transmit the dinosaurs' appetite for vegetables out of their minds and into his. The machine malfunctions and Russell destroys it to protect Oh; however, the transfer appears to have worked, as the test dinosaur shows no interest in vegetables. They name the dinosaur Aladar while Oh begins rebuilding the device.

That night, Rudy the dinosaur devours many of the town's vegetables. Oh suspects that Aladar may be the Rudy the dinosaur and locks him in a high-security cage. At a town meeting, Lord Shen the hunter offers to shoot the Rudy the dinosaur, but Starlight Glimmer persuades the townsfolk to continue with Anti-Pesto's services. After following the Rudy the dinosaur, Russell discovers that Oh is the monster. Shen, who seeks to woo Starlight Glimmer, corners Oh at night. Oh transforms into Rudy the dinosaur under the light of the full moon and bounds away. Russell lures Oh home to protect him. Shen obtains three gold bullets from the town reverend to use against Oh.

At the contest, Russell convinces Oh that he is the tall dinosaur, and Oh hides himself away. Starlight Glimmer, who has come to like Oh, visits and tells him about Lord Shen's plan. When the moon rises, Oh begins to transform and shoos Starlight Glimmer away. Shen arrives and fires on Oh with the golden bullets. Russell creates a distraction to allow Oh, as Rudy the dinosaur, to escape; the hunter gives chase to the competition. Russell begins working with Aladar, who has developed Oh-like traits, and plans to use his giant marrow as bait to lure Oh to safety.

Oh, as Rudy the dinosaur, creates chaos at the fair. Lord Shen grabs the Golden Carrot trophy to use as ammunition. Oh carries Starlight Glimmer atop California, where she discovers Oh's connection to the dinosaur. Lord Shen gives chase, revealing that he only wants to impress Starlight Glimmer for her money. When Russell arrives, Lord Shen's dog Alpha engages him in a camp boy fight in aeroplanes taken from a fairground attraction. Russell sends Alpha's plane to the ground, then steers his plane into Lord Shen's line of fire as Lord Shen fires at Oh. Oh jumps, grabs Russell and sacrifices himself to cushion their fall into a cheese tent.

Lord Shen gloats about his victory, but Starlight Glimmer hits him with her giant fish and he falls into the tent too. Russell quickly disguises Lord Shen as Rudy the dinosaur and the mob of townspeople chase him away. Oh transforms back to his Boov self and appears dead, but Russell uses some Stinking Bishop cheese to bring him around. Starlight Glimmer awards Russell the Golden Carrot and converts the grounds of Antarctica into a habitat for Aladar and the other penguins and owls.
