Bonesaw- Podrick Security System

The young tinker leaned away from her garden, her hands covered in dirt and her own bio-processed waste.  A ‘pod’ that existed as a loose spiral shape hooked around her ear twitched, then burbled, “Urmurgle.”
...

The pod that was hooked onto her ear burbled again, “Lurble.”

It heard and received supersonic impulses from creations she’d set around the compound, notifying her about movements.

“Guh,” the pod said.

“So you say,” she answered.

“Guh!” it said, more excited.

“Uh huh.  But if someone really wanted to come after me, Podrick, they’d figure out they needed to convince you.”

“Guh!”
...

“We followed the instructions we were given!  We pet the toad!” the woman called out.

The woman was Sarah.  The Valkyrie creation with the neat purple eyes.  A familiar face, but she was in the company of a stranger.  Valkyrie was nowhere to be seen.

Of course Sarah knew to pet the toad.  She had come for visits.  Petting the toad transmitted a signal to the pod, and the pod told Riley the coast was clear.  Maybe clear.
