Pookies don't stay young forever. Almost all of them grow up at some point. Here's the page all about that, as well as the process of becoming a Mumu or a Duh Duh!

Pookies are aged around newborn to about eight. They grow slowly.First, the mumu may adopt a tummy (unborn baby) or an egg. When the pookie is born, they may turn red and will need to be warmed, cleaned and clothed. Your newborn or new-hatched may have to sleep with you in bed for a while, until he or she is old enough to sleep in a separate room. Newborns will have to sleep in a crib and

can only drink milky or formula. Soon, you will be able to take your pookie out of his or her crib and he or she may learn to sit up. A few days later, he or she may start rolling on the ground or even crawling! When your pookie starts to crawl, he or she is not a newborn anymore. Your pookie may start saying short phrases such as "Goo!" and "Eh bah!" You will need to start giving your pookie some mush (baby food). Then, at around age two, they will say that they grow teeth, then grow hair. They may have a birthday. They may also change their clothes every day to look a little older. A while later, they might put on a pair of sunglasses, then at this point you will have "the talk" with them; talk to them about changing colors. Changing colors is like puberty

in Club Penguin. Girls will probably turn peach and boys might turn tan; and sometimes they'll stay yellow until they are a biggy.

After that they will probably start waking up by themselves and going to stool every day. You might get a little lonely that your pookie is all grown up, but don't worry about it, you can always get another one.

Middles are about age nine through 13. They try to act like older teens but they are still kids at heart.

They still like theme parks and they still want birthday parties and all that. They might ask for a cellphone or iPad or an electronic soon. That's when you know that they're growing up into older penguins. Their colors might change again. Guys will stay the same color and girls might change into tan. They may start going to sports and other activities and they will start losing the family side of their lives. They might even spend more time out of your house than in it.

Biggies up too. They usually age from 14 to 18 years old. They will probably sit you down for a talk and say they are going to college/university. They also might say they are 'running away' with their boyfriend/girlfriend if any, or getting married or something like that. However they wor

d it, they're leaving the house. Remember to friend the biggy in case if you forget their name or they can visit you, and you can visit them. Sometimes they'll have a pookie of their own! This is when the cycle starts over again.


Adults will grow up too. They are aged from 18 - 50. They can age higher, though.

Adults are called Mumu, Mommy, Mama, Mom, Mummy, Mum or Missy if female and Duh-Duh, Dudu, Dada, Dad or Daddy if male.


Even adults need to grow up at some point. Their children will probably be grown up by that point too. They say things like "walks slowly" or "falls down stairs" and eventually change their look. To set things straight, they often just say "is getting older." They may change their hair to blonde or something grayish. Then, commonly, these penguins switch out their sunglasses for regular glasses. If they have the cane item, they use that, too. Eventually, they will die. The family may have a funeral. After this, many penguins log off or start a new life at the Pet Shop. Most live up to 80 or 90. Rarely, grammas and grampies will age over 100 years old.


  • Each year is about two Club Penguin days. However, pookies and other fam fam members don't celebrate their birthday that often. Pookie and biggy years are usually longer, about three-four Club Penguin days, since those years are the most important parts of their lives. This is not always the case however.
