They are encountered in The Duke's Archives, after the Chosen Undead is taken prisoner by Seath the Scaleless. They are initially aggressive due to the alarm being turned on. If the player dies or turns the alarm off, they will cease to be aggressive and return to their alcove, only attacking if attacked.
Outside Big Hat Logan's cage in The Duke's Archives, two passive Picasas are huddled in the corner, crying with the voices of women. If they are killed, they drop the Bountiful Sunlight and Soothing Sunlight miracles, regardless of whether the player is in the Princess's Guard Covenant. They do not respawn.

- The name of this creature may originate from the Russian word "русалка" (pronounced "rusalka"), which means "mermaid".
- It may also derive from the Telugu word "piśācī" (pronoucned "pisasi"), meaning "witch".
- The Serpent Men seem to fear them, as immediately after freeing the Pisaca they promptly run up the stairs away from them, not even bothering to attack the player until they are at a safe enough distance.
