was watching penguin week and realised that they waddle and don't walk - thought that this may be down to them not having any knees!

Yes. Penguins appear to have very short legs and no knees because only the lower leg is externally visible. Their knees and upper legs are feather covered, hiding them from view. This also means that penguins never get cold knees!

yes, penguins do have knees, although they may not be seen even from close up, there knees are actually covered up by a very soft flap os skin. this flap of skin is also used to keep the chiks from freezin in the -35 degree farenheight tempratures of the winters. if my answer has not been helpful enough to you, try buying the imponderables book entitled "do penguins have knees' by davi feldman. in this resource you will find three pages of infor mation on this subject.

Yes, penguins are birds (Aves) in that they have feathers, lay eggs and have forelimbs modified as wings, but in this case used for swimming. They also share all the other characteristics of birds, being warm-blooded (around 40 deg C) and having a reduced reproductive system (one functional ovary or testis).
No, penguins use their wings (called flippers) to propel themselves through water rather than air. Because water is much more dense than air, penguin wings are shorter and stouter than the wings of flying birds. Penguins are also much heavier than similar sized flying birds and have solid bones rather than weight-saving air-filled bones. While these characteristics enable penguins to efficiently "fly" through water, they have had to sacrifice the ability to fly in air to do so
Yes, like all other birds, penguins have feathers. Penguin feathers are short, overlapping and densely packed. The outer part of the feather is waterproof while the inner down section traps an insulating layer of air, keeping the penguin warm in the sometimes freezing water. Unlike those of flying birds, the feathers on a penguin wing are very short.

No penguins do not have knees, and that is why they waddle. Penguins do not move fast on land which is why if they need to move fast on land they will often slide on their bellies, and head for the water. Once in the water look out catch a penguin is not an easy task.

penguins bodies move left and right when they walk, so i guess they dont have knees.

yes, they are very close to their tummies, their hip bones being short like those of chicken.
