Have fun playing karaoke with your favorite Hello Kitty! The microphone lights up to the rhythm, which may spark an interest in the joy of singing. The buttons are, from top to bottom: Rhythm button, Instrument button (flute), Instrument button (cymbal), Melody button (4 songs in total) - B-U-Z-Z, B-U-Z-Z / Do-Re-Mi / Twinkle Twinkle Little Star / The Bear Went Over The Mountain Playing with Hello Kitty will help develop your child's expressiveness and sense of rhythm. Perfect for pretend play and singing games at home. This is a used item that a child has played with, so the sticker is slightly peeling, but the sound and lights have been tested and are working, so you can still play with it. Batteries are included, so you can play with it as soon as it arrives. Stored in a pet-free, non-smoking environment. I try to respond immediately and ship the same day to ensure a smooth transaction. Thank you for looking.
