Tat is a black and white, cat-like character who first appeared in Klonoa 2: Lunatea's Veil as the partner of Leorina. She appeared as a playable character in Klonoa Beach Volleyball.

Tat's appearance resembles that of a cat. She is black and white and only has one of her yellow eyes open. She floats in the air to move, as she has no legs which are instead replaced by her tail and a strange green ring-like object. She also has blue buttons down the front of her body and long sharp claws.

Tat's personality is very varied depending on her status. In her normal form, she& loves to wind people up and she does so on several occasions whilst talking to Klonoa and his friends. Tat also cares about Leorina and is shown to be protective and worried about her after Leorina was brought back to her senses when she was consumed by sorrow.

Her two different forms also have different personalities and have contrasting opinions on Klonoa himself. Her black form doesn't appear to like Klonoa very much, occasionally taunting him and even calling him a "perv" after he catches her on the Jungle Slider (though is should be noted if you catch the white form first, she also calls you a Perv). Her white form, however, acts almost the opposite. She refers to him as "darling" at one point at the Joilant Fun Park (to Klonoa's obvious confusion and annoyance) and even helps Klonoa (and the player) to catch her by instructing how to use a Kiton to reach the ledge she's on. However, this could be due to her teasing him.
