Twisted Pebble

Pebble is the sharpest sensor on the roster. His direct vision of 125 is the longest of the 37 with data, ahead of Gourdy's 100, and his circular vision of 35 is tied for 3rd of 40. Hearing reaches 200, 6th highest, and attention span is 3 seconds. Add a chase speed of 24, tied for 3rd of 37 with Glisten behind only Gourdy and Bobette, and the result is a Twisted that spots you early and then keeps pace with almost everyone.

The wiki lists no special mechanic, because none is needed. His walk of 10 is ordinary, so the exposure comes from how far he sees, not from how fast he patrols. The counter is to stay behind cover across long corridors and open rooms, since a straight sight line of 125 covers most of a floor section. A Toon with 5 stars of Movement Speed, like Pebble's own, is among the few that can stay ahead of a 24 chase, and that Toon also has 4 stars of Stamina to sustain it.

Pebble is a Main Twisted, so he is forced about every 20 floors. At 100% Research you receive the Bone trinket, giving 25% extra walk and run speed for 4 seconds after picking up an item, stacking up to a cap of 40.
