Enemies

Ordinary Chickens

CI3Chicken

Health:
Chapter * 100 (Umbrellas have the same amount of health)
Rarity:
Very Common (Default Variant), Rare (Terminator Variant)
Attack:
Ocasionally shoot an egg

Reward: 1-2 different units of Food, occasionally Powerup, checkered Chickens before the last chapter 3 Coins (since 3.10)

Points: 900 + Chapter * 100

Description: Ordinary Chickens are the most common Chicken troops you'll get to fight and your main threat. Their attack is simple - shoot an egg downward. Although they might seem quite easy, their real strength lies in their sheer numbers. In most of the waves you'll get to fight hordes of these, all ready to shoot an egg at your face, and this gets harder in the later sections of each game, as their eggs become faster and get shot at a quicker pace.

They're also very versatile, being capable of doing numerous things, such as homing in on you or staying in large groups.

Two variants of them exist - the default variant, described above, and the terminator variant, homing in on you. The 360°, berserk and umbrella variants from The Next Wave are gone.

Appearance: Their appearance is simple. They're normal Chickens that wear a vest. They look much more detailed compared to The Next Wave, now that their vests aren't body textures, their beak looks more natural, they can blink, and they have tongues.

The Christmas edition gives them Christmas hats, and the Easter edition turns them into Hatchlings.

Balloon Chickens

BalloonChicken

Health:
75 + Chapter * 25 for each balloon and the Chicken holding it
Rarity:
Uncommon
Attack:
Ocasionally shoot an egg

Reward: 1-2 different units of Food, occasionally Powerup

Points: 4000 + Chapter * 1000

Description: Balloon Chickens are special variants of Ordinary Chickens. They only appear in three waves. They float around, holding onto their balloons. Once every balloon is popped, the Chicken holding it will fall. It's worth killing them, as they give much more points compared to ordinary Chickens.

Appearance: Their appearance is simple. They're normal Chickens with a red vest, holding onto colored balloons.

Editions do not affect them physically, though they retain some things from ordinary Chickens in the Easter edition (different eggs, higher pitched clucks).

Asteroids

AsteroidCI3AsteroidRedCI3

Health:
75 + Chapter * 25 (smaller ones), 150 + Chapter * 50 (medium-sized ones), 225 + Chapter * 75 (big ones)
Rarity:
Common
Attack:
None

Reward: 1 Coin, occasionally Powerup

Points: 50 * Chapter + 50 (smaller ones), (150 medium-sized ones), or 350 (bigger ones)

Description: Asteroids are common obstacles in the series. Although they have no attacks on their own, they're still dangerous, since they're fast and they come in huge numbers. They come in three different sizes, and two variants, although the variants only differ in their textures. They appear in Waves X6 in regular chapters, and they have a chapter dedicated to them, Meteor Storm.

Appearance: Their appearance is simple. They're big clumps of rock, which are colored either red or gray. The color does not make them different.

In the Christmas edition, gray asteroids turn into snowballs, while red asteroids are unaffected. The Easter edition does not alter them at all.

Description: Chests are special versions of asteroids, only present in the Bonus Challenge! waves. Their health and score are constant, that is, they always stay at 100 and 1000 respectively. They still speed up every chapter just like regular asteroids. They drop much more coins compared to regular asteroids.

Appearance: Their appearance is simple. They're colored chests.

The Christmas edition turns them into presents, and the Easter edition turns them into egg baskets.

Comets

Rarity:
Uncommon
Attack:
None

Reward: 1 Coin, occasionally Powerup

Points: 1000

Description: Comets are similar to ordinary asteroids, except for that they're much, much bigger than them. The Narrator claimed that they go faster than the speed of light, and convinced the Hero to go along them. They only appear in their dedicated chapter, Comet Chase.

Appearance: They're big purplish rocks which have a purple comet tail.

The editions do not alter them at all.

Description: U.C.O.s, or Unidentified Chicken Objects, are returning bosses in this game. They appear four times on your journey, each time armed with different weapons. You're able to lock on/attack both the main saucer part and the weapons, but only attacking the saucer will deal damage to it. Its arms can be passed through, however it's not recommended as you might easily get killed by the U.C.O.'s weapons.

Above the saucer part is the cockpit, inside of which a green ordinary Chicken resides to control the saucer.

On the fifth crack, the protective shell explodes, directly leading to phase 2. The Yolk is freed, and it's only able to wobble around, trying to hit you. There, it has 200000 health. Once its health is depleted, it explodes and splats as a fried egg on the screen.

It's a huge egg with a metal ridge below the center, dividing the spherical part from the more oblong one. On the oblong part rests a window which is surrounded by five laser cannons. The Yolk rests inside of the giant structure. It appears to be its power source, and it can use the machine however it wants.

The Easter edition makes its shell rainbow colored, while the Christmas edition does not change it at all.
