look up any word, like porb:
 
1.
A scourge in Orre, one of the many regions of the Pokemon world.

Whereas the other villainous teams have their grunts in plain view on the ground, Cipher trains its various Peons to hide on the ceiling, waiting in ambush for unsuspecting intruders. When one such intruder approaches, they drop down, call out their Pokemon, and attack immediately.

The name comes from "ceiling cat".
Ceiling Peon is watching you infiltrate.
