What is the real first name of the beloved blue ‘Sesame Street’ Muppet known as “Cookie Monster”?

My beautiful little daughter told me one day that the cookie monster frightened her as little child. It made me feel sad that I didn't realize it at the time. She didn't tell me 'til she was about 40 yrs. old.

I like the Cookie Monster .. Sesame Street is overall educational and kids need to be watching these type of shows. Keep in Me want cookie ..
