The Grim Adventures of Billy and Mandy Wiki

Poppin Lockin is the father of Irwin's mother Judy making him Irwin's maternal grandfather.


He is a mummy, short, fat, and has green skin with his bandages over his eyes. He also has a Yiddish accent, even though the rest of his family is black.


He was shown to be a tyrannical dictator. Despite that, he seems to love Irwin a lot, as he wanted him to follow in his footsteps.

Like most elderly people, he wants his family legacy to be carried on through a younger generation.

Unlike his daughter Judy (who doesn’t speak any English at all), Poppin Lockin is able to speak in human words.


He tried to get Irwin's mom to rule like him, but she refused, and they never spoke to each other for thousands of years.

He awakes from his coffin and visits his grandson Irwin and told him that he was next in line to be Pharaoh, which sparked a battle of wills between him and his daughter, who tried to dissuade Irwin from it. In the end, though, Irwin agreed to do it (as Poppin told him Mandy would fall for him if he did). By the time the pyramid had been finished, Poppin Lockin revealed that a pyramid is an Egyptian Pharoah’s tomb and that Irwin would be buried alive. Many years into the future, Poppin Lockin is still yelling at Irwin inside his tomb.
