While Sasuke was upstairs, Heiji snuck over to trail the rotten meat up to the stairwell. They didn't have to wait long, either, before the first of the robots came sniffing up to the bait. More followed, until there were several of them (wow, that bathroom didn't even hold that many people) all crowding around the bag Heiji had left on the first floor landing.

Heiji peered down at them; yes, excellent, they were bunching up. He made his way over to the gurney and gave Sasuke an okay signal.
