Review on 🎤 Disney Frozen 2 Karaoke Sing Along Microphone: Built-in Music, Flashing Lights, Pretend Mic - Perfect Kids' Toy- Karaoke Machine for MP3 Players! by David Batte

Plays the "let go" part and the "summer" part. My daughter practically ignores Olaf's song lol. It also lights up at the end of the microphone. You can connect it to an MP3 player and sing along to the songs on it, or you can tuck the cord into the microphone stem and keep it safe and out of the way. It still works despite many crashes and multiple uses. My main complaint is that we had to put new batteries in less than 12 hours. She got it for Christmas and the next morning it didn't work. Luckily, a new battery fixed the problem and it's still working.
