Kai: What's going on... (He and Nya start screaming.)
(They arrive at the Fire Temple.)
Nya: The Fire Temple? Boy, are you feeling homesick, Flame?
Kai: Maybe he forgot his toothbrush.
(Flame roars and opens up the entrance to the Fire Temple.)
Kai: Flame, why did you bring us back here?
Nya: I think he wants to show you something.
Kai: (Being nudged by Flame.) Okay, okay. I'm going.
Kai: Ahh... so that's what you wanted to show us... a secret entrance to the Underworld. (Kai accidentally slips and lands where the Skulkin are and prepares to take action.)
Wyplash: Huh? Ninja?! Attack!
(A bunch of Skulkin Warriors charge towards Kai as he attacks and disarms them. They all grab Kai's feet.)
Kai: (Attempting Spinjitzu.) Ninja, Go! (This has no effect as they still tightly hold his feet.)
Nya: Hold on, Kai! We're coming to help! (She and Flame fly towards Kai.)
Kai: I can handle it.
Nya: No you can't, stupid.
Kai: I'm formulating a plan here.
(Flame breathes out fire to make the Skulkin retreat back to the Underworld and seals them in with a couple of boulders blocking the entrance.)
Nya: Yep! I don't think their boney butts will be bothering us for a while.
Kai: See? I told you I'd think of something.
Kruncha: You dummy! (Slaps Nuckal.) You left the stove on again, didn't you?!
Nuckal: No, you did!
(The episode ends with the two fighting each other.)
