Chicken Little kisses Abby passionately. This is played for sweetness.

Floating eyeballs, hearts and brains can be seen on the spaceship.

UFO's creatures are outfitted with weapons.

After Chicken Little rings the town bell to warn everyone about the pending doom, the citizens panic and flee, with some bowling over others. During this, a fire truck ladder smashes through a car's windshield, causing the driver (who's okay) to lose control and strike a fire hydrant that flies through the air and hits a water tower. That then causes the large holding tank (in the shape of a ball) to break off the tower and then bounce and roll through town, sending people fleeing as it smashes through a wall, then through a movie theater and over various cars (no one is hurt).

None.

In the spaceship scene, there is a Jumpscare when Kirby (the baby alien) opens his eye.

a spaceship turns invisible before the protagonist is able to show it to the townspeople, they run to its location but don't make it in time (this will be intense for children who want chicken little to prove he's telling the truth).

When Chicken Little ring the bell to warn everyone by saying "The sky is falling!", everyone is panic and scream and lot of chaos in the town. Lot of wreck such as car, watertower, building and status.
