That's My Mummy is the 13th episode from season 4 of The Grim Adventures of Billy & Mandy.


Billy and Irwin were playing in Irwin's house. When Billy went to bathroom he suspected that he saw a mummy. Then things started pretty bad for him because of the curse of mummy. Snakes kept jumping on him or cockroaches come instead of water and he has to run out naked. When Mandy and Grim were fed up with it they decide help him. They got in Irwin's house. When Billy made them see the place where he saw the mummy they found nothing but a secret room below it! They found that it was an Egyptian room where Irwin mum came out. At last they had dinner with the Irwin family.

They came to know that Irwin's mother is really a mummy.
