The next day, Winston comes running to the den, urgently.

Winston: Kate?
Kate: Hi, dad. Good morning.
Winston: Where's Humphrey?
Kate: He's back there.
Winston: Humphrey!
Humphrey: Winston! Sorry about that. I didn't here you coming
(Winston just sighs)
Kate: Dad? Is everything alright?
Winston: I didn't think so. Hunter's outta his cage!
Humphrey: WHAT? But i thought he was...
Winston: Not anymore. He killed Hutch.
Kate: Oh my god!
Winston: Yeah, Hutch's dead!
Humphrey: That dirty bastard!
Lilly: (Comes running to them) Is everything okay?
Humphrey: Hunter's outta his cage. He killed Hutch!
Garth: What? That's impossible!
Winston: It looks like he created a weapon, so strong it could destroy the whole valley.
Humphrey: Then we gotta go and stop him.
Garth: I'm in
Lilly: Count me in too!
Kate: I'll always be with you
Humphrey: Awww, Kate. I love you!
Winston: I don't think you two got time for that now!
Humphrey: Oh yeah! Let's go (stops for a second) Wait, wait, wait! How are we gonna do this? I mean, how can i stop something that can kill us all?
Winston: Don't forget this, Humphrey. If you believe in yourself, you can anything you want.
Humphrey: Believe in myself. Cool.

With that, Humphrey, Kate, Lilly and Garth set off to stop Hunter from destroying the valley. Humphrey shares his goodbye with Sam:

Sam: I know that, but you'll be around weird wolves, weird places and weird food! Please don't go!
Humphrey: Sorry, dad but i gotta go and do this. Cause, you know i'm the leader right now and it's kinda my job to protect the valley. If i don't, then what am i?
Sam: You're my boy!
(short pause)
Sam: (not sure of it) Right?
Garth: Dude, are you coming or what?
Humphrey: It's gonna be fine, dad. I'm coming back.
Kate: Don't worry, Sam. We'll back before you can "Piece of cake". (runs off)
Sam: (has a sad look on his face) Piece of cake.

The four later found out that Hunter build a huge tower in a valley in Yellowstone Park. So, off they go to destroy the weapon and put Hunter back in justice. During that, the four found a den for the night, but Humphrey has a dream of him and his parents.

(in his dream)
Humphrey: Mom! Dad! Is that really you?
Tom: Oh hey, son. What's up? You're back!
Humphrey: What?
Sarah: Sweetie, what are you doing here?
Humphrey: What do you mean what i'm doing here?
Sarah: We replaced you with this beautiful little carrot!
Humphrey: What? A carrot?
Tom: Yeah! It's quiet, polite and in fact, it's got better fighting skills than you.

The carrot attacks and starts beating Humphrey, and this causes him to wake up.

Humphrey: What the hell? Damn! (runs outside) Replaced with a stupid carrot and it fights better than me. Yeah, right. (punches a tree, a raindrop falls on his head; punches it again and more raindrops fall; Humphrey freaks out)
Humphrey: What the hell is wrong with me? Damn! Damn! Damn! Damn!
Kate: Humphrey? Are you okay?
Humphrey: Kate! (looks at her) Yeah, yeah sure everything's fine, trust me. Everything's fine.
Kate: Then what are you doing up this early?
Humphrey: I.... i.... i couldn't sleep and.....
Kate: Humphrey, why are really out here?
Humphrey: What do you mean? It's just...
(Kate gives him suspicious look)
Humphrey: I just found out that my dad isn't actually my dad.
Kate: Your dad.... you mean Sam, the goose?
Humphrey: Yeah, that's him.

There's another short pause.

Kate: That's gotta be quite shocking for you, huh?
Humphrey: Kinda.
Kate: And that's bothering you?
Humphrey: Bothering me? Oh c'mon! How could this be bothering me? I mean, i'm the pack's leader now, like you. You know, you're all tough and sexy, and that's what i like about ya, Kate.
Kate: You swear you're not lying to me?
Humphrey: Yeah.... uhhh, cross my heart, hope to die.
Kate: Well...
Garth: What's happening here?
Lilly: You know, Garth. Humphrey's got dad problems.
Garth: I can see, you're freaking out, buddy.
Kate: Humphrey!
Humphrey: I'm not freaking out. I'm freaking IN!
Kate: Humphrey! We're here. Yellowstone Park.

With that, they head off to find Hunter and stop him.
