Jimmy Neutron: Planet Barnyard

Jimmy Neutron: Planet Barnyard is a 2008 computer-animation crossover film based on the Nickelodeon animated television series The Adventures of Jimmy Neutron: Boy Genius and Back at the Barnyard.

Plot
Jimmy Neutron and his friends are about to go on a field trip to The Retroville Museum. When his friends arrive at the bus stop, they miss the bus. Jimmy tells his friends not to worry, as he brings his rocket ship which he reveals to be their real mode of transportation, and their real field trip. His friends are angered that Jimmy did not consult them on his plans, and soon the rocket ship's pulsed rocket motor fails. Everyone is forced to abandon the rocket ship and board Goddard's ship form as the rocket ship collapses. Everyone blames Jimmy for causing all of this and lose hope of being saved. Hours later, Goddard's ship form starts to run out of fuel and Jimmy and his friends fall down to the far side of town.

The next morning, Jimmy and his friends wake up stranded and wander down the road on their way back to school. But instead of school, they end up in the countryside, and eventually run into a farmer. Jimmy and his friends ask the farmer for help so they can get back home. The farmer agrees on one condition: he'll help them, only if they clean his farm.

Jimmy and his friends have difficulty adjusting to days on the farm, but with the help of Otis, Pip, Freddy, Peck, and Pig, along with a dog named Mary, they succeed in earning their chance to go back home. They spend Thanksgiving with the animals, and Goddard begins to fall in love with Mary. However, one night, a pack of coyotes, lead by Dag, attempt to kill a chicken on the farm. Jimmy and Goddard try to save the chicken, but the bird ends up dying and the farmer mistakenly believes Goddard to have been responsible. Jimmy tries to convince the farmer that it wasn't him, but the farmer doesn't listen. The next morning, the farmer takes Goddard into the woods in order to put him down, but is attacked by the coyotes. Jimmy, Goddard, and their friends, along with the barnyard animals, manage to fight the coyotes off, and they get the injured farmer home.

Jimmy's heroics make the papers, allowing his parents, Judy and Hugh Neutron, to find out where he is. The farmer informs Jimmy and his friends of his trip back home and he departs the farm. Although initially Jimmy and his friends are happy to be back home, Goddard soon begins to miss being on the barnyard.

Sometime later, Goddard, missing Mary, becomes depressed. The next day, Ms. Fowl announces a field trip to the farm. Jimmy tells Goddard about the field trip and Goddard gets excited. Eventually, Goddard is reunited with Mary, who reveals to him that he is now a father, unveiling three puppies. The film ends with Jimmy and his friends watching the barnyard animals running a party and they decide to dance along with them.
