You must play a different sort of mini-game at each tower, in which you try to plant the Shadow bug on Cait Sith in various ways.
Cait Sith Coig is at the J-8 tower. You must shoot her when she remains visible for a long enough time.
Cait Sith Seachd is at the I-7 tower. You must assist Lilisette in playing a Red Light, Green Light game with her.
Note: When Lilisette puts her hands on her hips at the end of a move, she will descend two steps the next time you tell her to move.
Take care at this location, as smilodons may aggro after exiting the game/cutscene.
Cait Sith Aon is at the H-8 (outpost) tower. You must play a game of Red Light, Green Light with her.
Cait Sith Ceithir is at the G-9 tower. You must assist Portia in playing a game of Red Light, Green Light with her.
Note: When Portia starts looking around anxiously, there will be a small delay between you telling her to go and her moving.
Cait Sith Tri is at the F-7 tower. You will turn into a chocobo hatchling and must chrip to get her attention and then chirp or turn your back to get her to move closer.
Note: You get 3 tries. If you fail a tower you must zone to redo it.
Retracing yourself and warping via Campaign Arbiter counts as zoning for the purposes of this mission.
After doing all 5 towers return to the southern most tower (H-10) and view the regal pawprints for a cutscene.

Cait Sith Naoi is convinced a traitor walks among her kin. Unmasking the turncoat requires that you attach a "shadow bug" to each of the Cait Siths scattered throughout the Beaucedine Glacier.
