Macaw is a flashy city with many neon signs. It is a hub of gambling with at least one casino (and likely others). Macaw does some manufacturing, as one fake diamond Louie found had a Made in Macaw label on it.
The luck vampire Toad Liu Hai ran a mystical casino called The House of Lucky Fortune in Macaw. Gladstone Gander visited it at some point prior to October the 14th, 2017 and was imprisoned there, so that Liu Hai could feed off of Gladstone's luck. Gladstone was later freed by his family and The House of Lucky Fortune was destroyed.
