Harveste Addams And The Prisoner Of Azkaban: Harveste reacts this way when his boggart turns into a scene involving fresh air, happy music, flowers, and kittens. It takes one and a half bottles of Vodka to calm him down.
He stepped forward, curious to see what it would change into. What was an Addams afraid of, after all?
The Boggart flickered, and disappeared into a pool of sunshine. Peppy music seemed to bloom through the air on the wings of a pine-scented breeze, lightening the shadows, inducing a spate of foot-tapping with its catchy riffs. There was a yellow, sunflower-patterned boot. It had three wriggly kittens, one green eyed, one blue and one silver. They mewled ingratiatingly and one tumbled out in a furry little heap.
There was a pot of flowers in full bloom.
Harry took a step back with speed. "Loki's womb…" He breathed with horrified despair. "It's awful."
Draco and Blaise watched Harry stumble into the common room, closely followed by an anxious Hermione.
"What on earth happened?" She asked them, her eyes on their friend. He was in the closet, throwing out skirt after skirt, blouse after blouse. "He's shaking."
"Boggart." They both said together.
"Oh no. What did it turn into? Some huge, slavering, scaly, blood-soaked beast?"
"Don't tease me so, darling." Harry moaned, desperately burying his hands into black lace and chiffon to try and forget. "It was the most horribly disgusting thing I've ever seen. The fresh air…the music…the flowers…"
It took a bottle and a half of strongest vodka before Harry could control himself, but he twitched every time someone even mentioned cats.
