He's green, he lives in a trash bin and he always wakes up on the far side of the bed.
His name is Oscar Grouch, and even people who watched "Sesam Street" as a child may find him a little confusing. Why is he green? How did he choose his home? And why is he in such a bad mood?
Spinney was introduced to the characters when "Sesame Street" creator Jim Henson called him in the early 1960s.
After Oscar Grouch was born as the grumpy Muppet – but originally, he was orange – Spinney had to give him a voice.
He looked at New York City's inspiration streets and found the Bronx driver who drove him to the meeting with Henson.
Despite the admirable intentions behind the character, Spinney initially believed that he may not be suitable for children.
The show proved to be a huge hit, and sometimes he was complaining about famous musicians like Johnny Cash and Billy Joel. And the character created different versions around the world: his cousin Moishe Oofnik appears in Israel, lives in an old car In Turkey he is called Kirpik and he lives in a basket. And in Pakistan he is Akhtar and his home is an old oil water.
Oscar may be a worldwide celebrity at this point, but To Spinney, he is just grouch who goes in great length to hide his heart of gold.
"I'm dealing with a mental unity, not me, even though I authorize him," wrote Spinney. "Oscar has learned the power of the puppetry".
