Tiff (voiced by Kerry Williams) is a character from Kirby: Right Back at Ya!. She is the older sister of Tuff and a friend of Kirby. She lives with her family at King Dedede's castle and is known to be the smartest inhabitant in Dreamland besides Meta Knight. However, Tiff is a high-strong individual who gets angry easily, and is sometimes quick to resort to violence (though she's not happy about it). Despite her intelligence, she tends to be very naive and idealistic, reflecting on her youth and inexperience.
