Peek-a-boo! Wanwan and Poppo's Maracas Pressing the button plays exercise songs and nursery rhyme melodies. Includes: Pika Pika Boo, Kiran Kiran Biroon!, Twinkle Twinkle Little Star, Elephant, Tulip. I'm selling it because I don't play with it much anymore after using it for a few months. There's a little bit of wear on the stickers.
