In the third episode, a Podling is briefly seen naked from the waist down, but only from the back.

One of the Skeksis beats a character to death, blood is seen splattered onto a near by cage. It is very shocking to say the least!

The skeksis are shown eating plenty of food, most of it apparently raw, including eyeballs and such. A skeksis has his own eye ripped out.
