The Human Pack-Mule is a harmless enemy that appears in the Attic. It is a strange, overweight creature with stubby arms and a zebra-like head. It listens to an odd sounding broken record on an old phonograph while sitting on top of a trapdoor. Ned needs to hit the phonograph with his yo-yo and a morbid ladybug creature will pop out and the Human Pack-Mule will violently and continuously bite at it with its sharp, jagged teeth. The trapdoor will then open up and Ned can fall through to a basement with the Furnace.
If Ned comes back later, the creature will be gone and the trapdoor still open.
The creature eating the morbid ladybug.
