Kuo-Toa are a race of subterranean/deep sea amphibious monstrosities, not unlike a pudgy and disgusting fish man. They are evil to the core, if you offered to buy their grandparents they'd take you up on the offer... assuming they hadn't already sold them. We're talking steals lollypops from children and sticks chewing gum to bus seats evil here, and an ugliness that'd make the thing from the black lagoon slurp back into it again.
Kuo-Toa live in a religious cult like structure, with priests at the top of the scale, down to non Kuo-Toan slaves at the bottom. (Surfacers, Svirfneblin, Drow - whatever they lay their fishy fins on), all in all they arn't the kind of creature you'd invite around for tea and cucumber sandwiches.
