Tiff (Fumu Parm in Japan) is Kirby's most steadfast ally and protector in Kirby: Right Back at Ya!, despite being initially disappointed that Kirby is not a dashing warrior as she had imagined. She quickly warms up to Kirby after he saves her from falling to her death, and she is the only one who can summon the Warp Star as cares about Kirby the most. She is the most intelligent resident in Cappy Town, but can be idealistic and stubborn, and (rightfully) suspects that King Dedede's plans are up to no good despite having no proof. She has a younger brother Tuff, and both are children of Sir Ebrum and Lady Like.
The iconic Waddle Dee is the most common inhabitant and regular enemy of Dream Land, largely peaceful and give no Copy Ability when inhaled. They have been around since Kirby's Dream Land, and their appearance has largely remained the same - with slightly pear-shaped faces, stubby limbs, and no mouth. Many, many variations of them exist, and in one case, a Waddle Dee is Kirby's ally in Kirby 64: The Crystal Shards, but most of them are Waddle Dees carrying various items, such as spears or parasols. In the episode Pink-Collar Blues of Kirby: Right Back at Ya!, they are speculated to be wanderers from across the sea.
