Pac-Man Ghosts from Costa Rica and Thailand - "Siamy" & "Costariky"
Siamy and Costariky are Pac-Man ghosts from Thailand and Costa Rica. Note that Siamy's name is based upon the original ethnic name for the Thai people who are Siamese. There are other groups in Thailand that are not Siamese like the Lao, Chinese, Falang, Burmese, and many others. Yet all are Thai by nationality, some groups have their own language and distinct cultures.
Thailand and Costa Rica are nations of the Isthmus at a juncture between oceans.
