Because they were neckromancers
Ivy.
Scare spray!
A saucer-er!
They make a Daily Prophet.
They were scared of sparks flying.
Going to kiss your grandmother goodnight and she slips you the tongue.
Because their horns don't work.
The giraffe and the aardvark were running neck and neck but the aardvark won by a nose!
A Neckromancer
