|The first penguin seen in the game can be found at the very beginning of Cool, Cool Mountain, atop the little hut.|
This baby penguin's name is Tuxie. Bringing Tuxie to her mother rewards you with the star Li'l Penguin Lost.
|The second baby penguin is found near the Mother Penguin in Cool, Cool Mountain, atop the little hut at the bottom of the level.|
Bringing this baby penguin to the mother penguin does not result in a star.
Unlike the baby penguins, there are several more instances of larger penguins. Two of which are in Cool, Cool Mountain.
|The first of the bigger penguins is the Mother Penguin of Tuxie.|
The Mother Penguin is found at the bottom of CCM, near the 2nd baby penguin, outside the lower hut.
||Also in CCM is the 2nd big penguin, found within the slide portion of CCM, in the hut at the top of the mountain.|
Once you complete the first star of CCM, Slip Slidin' Away, you can re-enter the slide and race this penguin.
Upon beating him in the race, you will be rewarded the Big Penguin Race star.
|The final Big Penguin is in Snowman's Land, found partway up the snowman.|
He aids you crossing in front of the snowman's face, blocking the snowman from blowing you back down to the bottom.
CCM infinite coins
The Mother Penguin may play a possibly important part in the CCM infinite coins route. Because the Mother Penguin gives a dialogue, Time Stop can be activated on the J 1.0 version of SM64. It is theorized that this penguin could play an integral role in performing the CCM infinite coins glitch. [expand on the route]
