"Yes, but Luna, exactly what does a Wrackspurt look like?", Hermione questioned sceptically. Luna had really grown on Hermione, but her fixation on imaginary creatures was becoming grating.

Luna extended her wand and muttered inaudibly, a trail of silver emitting from the end of it.

A small Patronus, barely larger than a thimble, danced in front of Hermione, it's tiny antennae wiggling in the air as it bobbed and leapt around her head, gleefully pulling at the unruly curls.

"There, that's exactly what a wrackspurt looks like." Luna replied, her eyes fixated on the fluffy little creature. She began wandering towards the lake, humming absentmindedly, the wrackspurt in tow.

Hermione was left standing, bewildered, and made a mental note to not dismiss Luna so readily next time.
