Accidental slip
JKR owns the Harry Potter universe, not me.
A very alternative ( and hopefully humorous) Voldemort solution.
October 31, 1981
Harry Potter was a fifteen month old baby, still undergoing potty training. When his mother Lily strted changing his nappy before putting him to bed, Harry jumped up and ran around the room, including in front of the doorway. Lily eventually had everything ready for him, and using her wand, summoned him from in front of the door, and quickly finished getting him ready for bed. She then sat down with him and his father James, while James was using his wand to amuse Harry.
Tom Riddle, aka Lord Voldemort, walked up the pathway to the front door of the home. A smile on his face as he anticipated destroying the threat to his rule. They were fools to have trusted in their friend, and now he knew their location.
As he approached the door he subconsciously noticed the door's sill was a few inches high. He blew off the door, and made a single step into the room, wand raised as he assessed the threats awaiting him. he laughed as he made a second step, his foot came down on something soft and squishy, he promptly lost his balance and fell backwards, his neck hit the sill and lost all ability to feel, move or talk, as he heard a snap in his neck.
James had rushed into the corridor as he heard the door explode, telling Lily to run with Harry. He was shocked as he saw Voldemort slip on Harry's poop and heard the crack as his neck hit the sill. As a prankster, he was quick witted, he promptly summoned Voldemort's wand and then transformed the body into a wooden figurine.
My story ends here, use your imagination as to how you want the story to finish.
Is it not more fun for you to use your imagination!
