Guppies: Good morning Mr...Grumpfish?! (The kids faces turned from glad to scared except Deema cuz her eyebrows stay the same and her mouth has a frown)
Mr. Grumpfish: What's so good about it?
Molly: Uh, Mr. Grumpfish? What are you doing here?
Gil: Where's Mr. Grouper?
Mr. Grumpfish: He's at the dentist. I'm your substitute.
Deema: Substi...wha?!
Mr. Grumpfish: Substitute teacher.
Nonny: A substitute is a teacher that takes care of you when your regular teacher's away.
Mr. Grumpfish: He'll be back later.
Gil: But what are we gonna do today?
Oona: Are we gonna do anything special?
Mr. Grumpfish: Nope. It's raining.
Goby: It's not raining, Mr Grumpfish.
Mr. Grumpfish: It might. I don't like rain. Too wet.
Oona: It's not going to rain. It's a pretty spring day
Mr. Grumpfish: What's so pretty about it?
Guppies: Let's sing about it!
