When Birds fly into a field, it will be drawn closer and closer to its center, altering their course. Unless there is an obstruction in the path of the bird, it will fall to the lowest point in the field. Pigs, as well as their structures are affected by the gravity field as well. However, with enough force, a Pig can escape a gravity field, but it will have a small chance of survival afterwards.
Gravity fields also function as atmospheres. It allows Pigs to breathe without the use of Bubbles. If a Pig is outside a field and is not in a bubble, the Pig will freeze and will die in a matter of seconds.
- Most episodes have BLUE-colored gravitational fields, but some are a different color. Red Planet has WHITE/BEIGE-colored gravitational fields, Eggsteroids has YELLOW/ORANGE-colored gravitational fields, and the Danger Zone has RED-colored gravitational field.
