Lambie: Happy Valentine's Day!
Doc: Wow, you did it again Lambie. The clinic looks even more amazing then last Valentine's Day.
Lambie: Aw, thanks. I just can't help myself. Valentine's Day is my favorite day of the whole year!
Val: Love your party, Lambie. But then, I love everything about Valentine's Day 'cause, I'm a Valentine. And it's my day.
Lambie: (softly) But it's supposed to be my day.
Lambie: Doc, I have something really special to show you. It's my super special Valentine's Day-
Val: Step on up and get a cuddle.
Lambie: Cuddle booth! (Gasp) What's she doing in there?
Val: Hey there snowman, you look like you could use a cuddle.
Lambie: (Gasp) That's my line...
Stuffy: Bet you never had a dragontine before, Doc. Get it? Dragontine? Valentine? Ha! I'm your Valentine!
Doc: (Giggles) Thanks, Stuffy. You're the best 'Dragontine' I ever got.
Val: (Gasp) Sparkles? I love sparkles!
Doc: I'm sorry, Lambie. I guess I was so caught up in Valentine's Day and my new toy I didn't notice how you were feeling. But, no matter how many toys' I have, no one can ever take your place.
