king boo (super mario sunshine)

A character from Super Mario Sunshine. He was originally known as "Boss Teresa" (Boss Boo) in Japan, but a sloppy localization resulted in him having the same name as the real King Boo in the English version.

Despite the uncanny resemblance, Boss Boo isn't really a Boo at all, but rather a product of Bowser Jr.'s doing, and is made out of goop. Defining characteristics that set him apart from the real King Boo are his lazy aqua eyes and ridiculously oversized tongue (which is big even by Boo standards).
