Her grandmother transformed into a harpy. Though a terrifying creature in its own right, seeing her grandmother's face on a great big feathery bird was hilarious. The Petunia boggart looked down at itself, clearly distressed and confused. It began to flap its wings and fly about haphazardly. It bumped into the walls and smacked into the ceiling, shrieking as it did so. The sight was so ridiculous, Ellie was doubled over with laughter. The other students were a bit unsure of what was going on, the harpy clearly scaring many of them. The only person who joined in Ellie’s laughter was her uncle Harry. With the swish of his wand, he sent the boggart back into the cabinet, and locked it shut.
