The Soul-Sucking Death Worm is a colossal monstrous worm that appeared in the episode "Dead at Eight".
After Mordecai and Rigby read The Hungry, Hungry Soul-Sucking Death Worm to Thomas, they pull a tab which releases the actual Soul Worm. Thomas tried to feed Muscle Man's soul to it but Mordecai and Rigby managed to lure it back into the book.
It's appearance is a giant reddish-orange worm with a giant mouth with little waving pieces of skin and no eyes.
- He is an obvious parody of The Very Hungry Caterpillar.
- The reason Thomas says that the book is his favorite is because he wants the Soul Worm to be released and feast on souls.
