Quina, you in darkness. Need some light. World big place. Many many foods.Quale
Quale's clothing resembles high ranking chef, which reflects his status as the leader of the Qu. His attire has rose-colored details, and, unlike the other Qu, he has a yellow curly mustache. Much like Quina and possibly the other Qus, he fights wielding forks, more specifically the Silver Fork (seen only during his boss battle).
In the Spanish and Italian versions of Final Fantasy IX, Quale and Quina are addressed as females (she, her, etc.), while Quan is addressed as a male.
Quale has a strong and somewhat stubborn personality, and is strict with her/his student, Quina. However, s/he recognizes Quina's effort to become a gourmand, and often rewards him/her during her/his frog catching.
Quale can first be seen when Zidane helps Quina catch a frog in the marsh near Lindblum. Quale comes in and berates Quina for being unable to feed him/herself. They enter Quale's abode further into the marsh, where Quale asks Zidane to bring Quina along on his journey so that s/he may taste exotic cuisine.
Once outside, Vivi comments Quale looks just like his "grandfather", Quan, who had died recently. When he goes inside to ask Quale about his grandpa, the Qu leader does a bad job of pretending that s/he "not know this Quan". It is obvious there has been some past disagreement that fostered dislike between the two.
If Quan's Dwelling is visited with Vivi and Quina in the party, Quan's spirit appears to praise Quina's ability to use his/her imagination, stating that soon he/she will be able to find sustenance without food. Quale appears and argues with Quan, who is revealed to be Quale's former master. Apparently, the aforementioned disagreement was due to Quale's inability to use his/her imagination when following the way of the gourmand. After this conversation, Quale decides to approach food differently and rethink his/her teachings.
All of the Qus' names begin with "Qu".
Quale and Quan's full names are given as Quina Quale and Quina Quan respectively, which would suggest that "Quina" is a clan name, rather than a personal name. Usually when saying "eat" in Japanese, it's 食べる (taberu), but 喰う, kuu (or quu) is another way to say it. This symbol, 喰, is specifically read as ku (or qu). The word is more informal, and just saying "qu" with no context makes it sound a name of a race.
