Alma: Wow! Doc, wanna be in our band?
Doc: Sure! Lambie can be our audience.
Stuffy: (Beat box noises) I'm a hip-hop dragon and I'm here to say, I like to roar most e-very-day. I'm big and brave and I got cool wings and a big blue tail, it's a dragon thing. So that's my story, they call me, Stuffy. Come on lets play if you're feeling eh...puffy? Pa-puffy, pa-pa-pa-puffy, a u-huuh-uh a u-huuh, a-Stuffy, sta-Stuffy. Uh-uh-uh-uh, that's me!
Lambie: Hi, Xyla. I'm Lambie. Oh, I love your music. Every time I hear it, it makes me wanna twirl!
Doc: You know, Xyla, when a key is loose, there's a good chance you might lose it.
Xyla: Oh! I don't like the sound of that! No one's gonna wanna listen to a xylophone with loose key syndrome.
Lambie: Well, I still think you sound pretty.
