Bad Badtz-Maru is a male penguin with spiky hair. His birthday is April 1. He is one of the few Sanrio characters that is marketed to both males and females. In Japanese, “badtz” (batsu) is a term for “X”, the cross signifying a wrong answer. “Maru” means circle or “O”, and signifies a correct answer. Thus, his name figuratively means “wrong-correct,” and is frequently represented by “XO”. Badtz-Maru has many different facial expressions and poses, but a common expression is of pulling one eye down and sticking out his tongue, a gesture equivalent to blowing a raspberry.
