Princess Boo, often referred to as Boosette, is a fan-created character that gained massive internet fame in late 2018 following the viral 'Bowsette' phenomenon. The trend was sparked by the Super Crown power-up from the Mario universe, which reimagines classic enemies as Princess Peach-like royalty. Boosette represents a regal version of the iconic Boo enemy, inheriting the ghost's signature trait of extreme shyness whenever she is looked at directly. The meme is widely used to illustrate social anxiety, bashful reactions, or to participate in the ongoing 'Crown' art trend. It remains a beloved template for fans of Nintendo-themed humor and internet-born character designs.
