Big City Greens the Movie: Spacecation[]
Nancy: Cricket, look, I don't know how long this signal will hold and we don't have much time. The asteroid's on its way and we gotta figure out a way to save Big City. Any ideas, kiddo?
Cricket: I... No, all my ideas are bad.
Gloria: Well, unless somebody thinks of something, WE'RE ALL GOING TO DIE!!!
Nancy: What Gloria means is, right now there are no bad ideas.
Cricket: [scoffs] Tell that to Dad. He said all my ideas are crazy. I'm startin' to think he's right. It was my idea to go to space, and look where that got everyone! If I tried to save Big City, I... I'd probably end up hittin' it with a second, bigger asteroid and double destroyin' it. (gets kicked by the leg) Ouch! What was that for?!
Nancy: Cricket Green, you listen to me. Sure, some of your ideas can be a bit crazy, but crazy problems need crazy solutions! I know you and your dad don't always see eye to eye, but you two are more alike than you may realize. You both do what's best for the family; you just go about it in different ways. And I believe with all my heart that if y'all could appreciate each other's strengths, there's nothin' you can't do. Cricket? (loses signal)
Cricket: Mom? Dang signal. Mom?!
Nancy: (signal comes back) You can do this.
Cricket: Hey, Dad?
Bill: Yes? What is it, son?
Cricket: I just... I just wanted to say... I'm sorry for what I said to ya on the asteroid. And for all of this. I just wanted the family to have the best vacation.
Bill: I know you did.
Cricket: If I hadn't hijacked our trip, none of this would have happened, and... you would've kept us safe like you always do! Everything would be better if I wasn't... If I weren't so... [grunts and yelps]
Colleen: The asteroid is slowing down, but we need more power.
Bill: It's okay, Cricket. I hear you. I may keep the family safe, but I know that playin' everything safe can be, uh... heh-heh... Dull.
Cricket: Heh...
Bill: But you; you keep things exciting. Without you, this family wouldn't be the same! You're bold, creative, and you take big leaps.
Cricket: You mean that?
Bill: With all my heart.
