She is athletic, energised and a bit of a feisty hamster. She was rude when she was jealous of the Ham-Hams. She called Hamtaro "crazy cranberry" and called Rosy a grape. She is always in her best act when Prince Bo is around.
Her Japanese name comes from the English word "Pretty" while her English name, Daisy, comes from a daisy flower because her suit and hair colour are yellow.
