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-ver-y day. I'm big and brave and I got cool wings and a big blue tail, it's a dragony thing. So that's my story, they call me Stuffy. Come on, lets play if you're Pa-puffy, pa-pa-pa-puffy, A u-huuh-uh a u-huuh, a-Stuffy, sta-Stuffy. U-huuh-uh-huh, that's me!
Lambie: Hi, Xyla. I'm Lambie. Oh, I love your music. Every time I hear it, it makes me want to twirl!
Doc: You know, Xyla, when a key is loose, there's a good chance that 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.
