Ernie's Bubble Band is fun bubble/music toy with unique underwater music sound. Child put lips to trumpet to activate music. If the child presses down any of the blue keys a motor is activated and bubbles will come out the front of the horn. (The rotating bubble wand has 4 openings) When the bubbles hit the switch located in the blower section, the tune being played changes. It will sound as if it is being played underwater. The ring of the trumpet is a spill resistant reservoir for the bubble solution. Press the green/yellow try-me button to hear a tune for a few seconds along with Ernie's voice, and then a few seconds of the same tune as being played underwater.
