Pookie Cycle is a life cycle of the sub-species babies in Club Penguin, here's a good look of learning the life cycle.

Life Cycle

Eggs (Unborn)

Like penguins babies come from eggs, however, these eggs are different and came from a different island somewhere around Club Penguin Island. They go to the Pet Shop and say "Free Eggs" or "Eggs for sale", they can only roll around and wait for somebody to adopt it. Pookies might use a blanket or the mummy costume to look like an egg. Eggs are very vulnerable: just stomp on them, crushing their shell. Although the egg shell gives them little defense. They can't even roll or speak, which makes no sense at all. It is currently unknown where these eggs came from.

Tummy (Unborn)

Tummy Pookies are by far one of the most outrageous kind of Pookies. They are innapropriate, sexual related roleplay by using childbirth (with words filled of details about birthing such as "bweginz to gwetz out of womby", womby meaning "womb") and they manage to avoid getting banned. Tummies are related to childbirth like humans in real life, which makes them totally inacurate and cringy. They are often spotted near the Hospital or the Pet Shop, sometimes near the Lighthouse due to hiding from public places. Tummies often says "Iz Fwee Twummy!" or simply "Free Tummy!" to get attention and let innocent penguins lure them into their bad roleplay. Tummies are very easy to kill, even more easy than their Egg counterpart or a normal Pookie since they are in fact "embryos" and embryos are very weak. In addition, Tummies manage to walk and talk before getting inside the mumu's womb, making no sense again. When born, they will use explicit words about birthing. It is very easy to kill them in this moment.

New Born (After Being Hatched Or Tummy Born)

After being hatched they will go to the pet shop. They won't know how to stand or speak sometimes. They sometimes say "Is newborn". This is when they get there yellow color. They will be treated with the most respect in CP to moms.

Pookie (Growing Up After Being New Born)

After learning to stand the pookie will soon start learning. They will most likely be adopted at this stage. The pookie may go to day cares or pre-schools. This is also when they get new toys.

Prep (10-12)

After being a toddler they will soon start acting like a prep. Example : The pookie will say "Ikr" "Idc". They will start acting like a prep and better spelling.

Teenager (13-17)

When being a teanager they will be have to be a model for there younger sisters or brothers. They will also hang out with other teenagers and say "Texts to Boyfriend". They will sometimes get a car.

Adult (18+)

When 18 or older they will leave there homes and than go to the CP University. This is when they pick their jobs. Mostly likely they will be a EPF Agent or a Coffee Worker. They also may get married and have their own pookies.

Elder (Final Stage)

When they are a elder they most likely carry a cane or have a beard. At this time they will be at a retirement home. After a few days or months they may die. And the cycle starts all over again.
