Nai-Nai, the box with the universe inside of her.

Nai-Nai is a shy orange cousin with the universe inside her. She is a box-like cousin who rarely shows her face. She was first introduced in Me & My Katamari then returns to Beautiful Katamari and Katamari Forever. Her face may show up when she is in a good mood, or when being extra careful, as shown by her animations when she rolls the katamari in Me & My Katamari.
