Choco Beak(チョコアタック, Choko Atakku?, lit. Choco Attack), also known as Choco Attack, is a recurring ability in the series. It is an ability commonly used by Chocobo enemies, which deals non-elemental physical damage to one target.
"Choco" is short for "chocobo". [view·edit·purge]The name "chocobo" derives from a Japanese brand of chocolate malt ball by Morinaga, ChocoBall(チョコボール, Chokobōru?). The mascot for this product is Kyoro-chan (キョロちゃん?), a bird who says "kweh".
食う / くう / kuu is a rough way to say "eat", whose volitional casual form is 食え / くえ / kue ("let's scoff 'em down!"), leading to Kweh!
