Baby Penguin

Tuxie is a baby Penguin that is lost on top of Cool, Cool Mountain in Super Mario 64. She needs to be reunited with her mother. Mario picks Tuxie up and carried her down the mountain, her mother located at its base. For finding her baby, the mother penguin awards Mario with a Power Star.

Tuxie is not actually referred to by name in the game and can easily be confused with another baby penguin who is also located on Cool, Cool Mountain. This latter penguin is located on the roof of the cabin next to Tuxie's mother. If Mario delivers this lookalike to the mother, she tells him that it looks nothing like her child (she says elsewhere that her child has her beak).

A baby penguin who may be a reference to Tuxie appears in Super Mario Galaxy in the second mission of the Sea Slide Galaxy.

Trivia

 * Tuxie's name comes from "tux", the shortened form of tuxedo, a type of formal suit that bears an uncanny resemblance to a penguin's feathers.
 * If Mario runs and dives near Tuxie, she will do a dive as well, making a different chirp sound.
 * If Tuxie is picked up again after being returned, her mother will get angry and follow Mario until he drops her.
 * Tuxie's chirp is similar to car alarms.
