Mums is a 5,000 year-old Egyptian mummy, but he can unwrap his bandages to reveal a "Grim Reaper"- like form underneath.
At one time, two archaeologists came to return Mums to the crypt in which they found him in order to get rid of a curse placed on them. Out of the four (questionably five if Ghoul is including) monsters who first tried eating the kids, he and Count Fangula were the only ones who are intelligent enough to speak basic English when Wolfie and Frankenbeans could not.
Mums has 703 brothers and sisters.
- The name Mums is most likely just a nickname, Mums real name is currently unknown.
- Mum's may have learned English from eavesdropping on those who originally unburied him.
- He's fond of rapping, as seen in The Hunchback of Hillhurst.
- Mums loves gambling, as seen in the "Shadowborg Saga".
