Pitch: Two neighbors are fighting and constantly trying to top each other, but then this new chick moves in to the house across the street. She turns out to be even worse than the two neighbors, so they decide to team up to get rid of her. They do so by mounting rockets to her house and giving her a one-way ticket to the moon. Neighbors become friends.
Style: I'm imagining this to be in a bright cartoony style. Very typical 3D animation.
Plot: In a seemingly peaceful neighborhood, we get to know this middle-aged man stepping out of his house with a soda and a newspaper. He goes and installs himself in his new hammock and just as he starts relaxing, we hear a loud and sharp lawn mower sound. It's the other neighbor mowing his lawn. This sound goes on his nerves, and as a response he throws a rock right in front of the lawn mower, effectively breaking it. The neighbors starts fighting, but suddenly stops when they sees a new chick is moving in right across the street. Trying to make a good first impression, they both try to behave like civilized men for once, but as it turns out, she's even louder than both of them, playing louder and louder music by every night. The neighbors can't take it anymore and team up to get rid of her.
The next night, they sneak up to her house and starts installing something on her house.
When the sunrise arrives, they're finished and runs back to their own property. Just as she wakes up and moves to a window, one of the neighbors brings up a remote control and presses a button. Four huge rockets on her house fires up and lifts the house into the air and off into the horizon. Neighbors shakes hands and becomes best friends.
Pitch: Two young siblings (a girl and a boy) are playing around, when one of them is nearly ran over by a trailer, but they continue playing. We change point of view and now the boy is playing all alone. It's made clear that the girl was killed by a trailer quite some time ago.
Style: A darker and more realistic/gritty art style.
Plot: Two young siblings (a boy and his little sister) are outside playing and laughing. While playing they're crossing a busy road with a lot of traffic and the girl is nearly ran over by a passing trailer. They stop up for a second before continuing playing.
The camera cuts to a nearby house. We're now looking over the shoulder of a person staring out of a window. From the person's point of view through the window we can still see the boy playing, but this time, he's completely alone - but seemingly still playing with someone. The camera turns around and zooms in on a old newspaper cutout surrounded by flowers above the fireplace. The picture and text reveals to us that the girl was ran over and killed by a trailer quite some time ago.
We're outside again, and the boy is still playing and laughing - alone.
