One of Bautista's trackable stuffed animals, the class of item used to probe the shifting Reaver corridors.
At the entrance of The Reaver Castle, Bautista tossed stuffed animals into the randomly shifting Honeycomb Hallways, telling each one to go as far as it could. Because he can keep track of where they are, they functioned as living survey markers.
He reported their positions continuously to Katia, who used the data to map the interior and identify the static edge honeycombs and the top center passage to the Throne Room.
Reconnaissance probe for mapping corridors nobody dared enter in person.
