Chocobo's Lagoon is a lagoon in the Salvage Archipelago in Final Fantasy IX. Choco can find Chocographs and Chocograph Pieces in the lagoon as part of the Chocobo Hot and Cold minigame. The lagoon can be reached easily by a sea chocobo, but can be accessed with a reef chocobo if the party has either the Blue Narciss boat, or Hilda Garde III or Invincible airships.
Originally, only half of the lagoon is searchable, but once Choco gains the ability to travel on deep water, the player can search the entire lagoon.
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!
