Children's birthday parties were chaotic enough without unexpected guests, but this really took the... cud.
"A cow?" sputtered one parent of the birthday-child.
"A fairy-godheifer, to be exact," clarified the ethereal shepherdess.
"At least it matches the barnyard theme," said the other parent tiredly.
Their child giggled atop the magical bovine, several other children eager for a turn.
"Does she grant wishes?"
"Dairy-based ones."
