My first Bumba piano offers two modes: In mode 1, you become a real DJ, and in mode 2, you play an instrument yourself! Play like a true DJ and choose your own theme, instruments, rhythm, and add fun Bumba sounds. With this piano, you can choose four instruments: Piano, Guitar, Flute, and Violin. Press the instrument you want to play, and the Bumba party can begin! You can adjust the volume, pitch, and speed of your song. Super fun and educational toy for the little ones. 3 x AAA batteries, included.
