As with real flowers, Petal-Chi needs to be taken care of. When you water her with her special watering can, you'll actually hear the water. Putting her in light also makes her feel good. You can gauge her feelings by watching her face. Right now my Petal-Chi is singing "I'll Be Working On The Railroad" and has the cutest happy face smiling up at me. Petal-Chi Sings 40 Different Songs, Its face changes with its mood, The Interactive Flower that Blooms, Part of the Robo Chi Garden.
