Yeah, she could see it now. The remains left bu the gulls strewn on the beach and the curious scavenger picked up the pieces.

"With great care," she chuckled again.

Ah, a handy puddle. Vanity wandered into such puddle of seawater looking for a critter.
"Here," she invited him closer. "See it's little head just there, hiding." She smirked.
"We need a rock," she explained, looking around for one big enough for the job.
