This is a cute and happy picture of four little mouse friends who are singing songs together! Each mouse is holding a songbook and singing notes that float up in the air like tiny musical bubbles.The first two mice are wearing adorable party hats. The first one has a hat with a little pom-pom on top, and he looks like he’s sleeping while singing! His friend next to him has a similar cozy hat, and they both seem so content, enjoying the music.The third mouse, who''s not wearing a hat, is really getting into the song. He’s standing tall and singing really loudly, maybe even hitting the high notes!The fourth mouse is very intrigued by his songbook. He''s focusing hard on reading the words so that he can sing them perfectly.All together, these mice are sharing a fun moment, making music with their sweet little voices. They are having a wonderful time, just like when you play and sing with your friends!
