When Bob Ogden came to visit the Gaunt Shack, Morfin was twisting it in his fingers, singing to it in Parseltongue:
"Hissy, hissy, little snakey
slither on the floor,
you be good to Morfin,
or he'll nail you to the door."
Behind the scenes
- The snake was known to be a species of adder.
- Harry Potter and the Deathly Hallows (First appearance)
