Pooldripp is found among other Kuo-toa in The Festering Cove, worshiping a figure called BOOOAL, the alleged Kuo-toa God of Murder.
The player can reveal BOOOAL's true identity, which will anger him and start a fight against only him. Killing BOOOAL will frighten the Kuo-toa, and they will quickly proclaim the player character to be Mahkloompah, their new god, and ask what to do next. The player character can tell the Kuo-toa to find a better name, build an army, stop their blood rituals, study the teachings of the player character's god, or just keep doing whatever they were doing until then. Regardless of what is picked, Pooldripp will attempt to comfort the player character by claiming the Kuo-toa will spread the player character's word violently.
Should the party fail to reveal BOOOAL's true identity, the Kuo-toa will aid BOOOAL in the fight.
