*Lupita Nyong’o discussed the wonders of skin on Tuesday’s episode of “Sesame Street.”

The Oscar winner praised the body’s biggest organ in a segment with Elmo, asking her new buddy, “Did you know all animals and people are covered in skin?”

With Nyong’o’s help, Elmo learned that he indeed has skin underneath his famous red fur.

The “12 Years a Slave” star went on to explain the functions of skin, ranging from protection to touch. What quality does she love most about it? “Skin comes in lots of beautiful shades and colors,” she said.
