Poppin Lockin is Irwin's grandpa.
He is a mummy, short, fat, and has green skin with his bandages over his eyes. He also has a Yiddish accent.
He seems to love Irwin a lot, and was shown to be a tyrannical ruler.
He tried to get Irwin's mom to rule like him, but she refused, and they didn't speak for thousands of years. He told Irwin 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). At this point in time, he has only made one appearance.
