Encountering the Fire Viper in Twisty Tunnels/Getting to the Ancient Terrasquid

Here is how the search for the Ancient Terrasquid begins in Return of the SWAP Force.

Later, they all came just in time in one piece as Rufus expect their return.

Rufus: So glad to see that you've all returned safely, Princess Twilight. And look! Your friend, Wheellock has graciously come to lend a hand.

Wheellock: No trouble at all, Rufus! (to his friends) Listen, Y'all, I brough y'all a girft! A brand new fishing pole! There's a fishin' hole down in the Under Hollow that's perfect for relaxin'. left the pole down there just for some of y'all. Feel free to use it anytime!

Twilight Sparkle: Thanks, Wheellock.

Wheellock: Glad to oblige, Princess.

Pinkie Pie: Weee!

Spyro: Alright.

Wash Buckler: That’s what I’m talking about!

Tree Rex: Booya!

Soon, the Portal Masters, the Skylanders, Twilight, SpongeBob, Mickey, Thomas, Mumfie, and their friends were making sure Woodburrows were in good hands.

Wild Flower: Isn't this place beautiful, Stealth Elf?

Stealth Elf: Yeah.

Cynder: This could not get anymore better than this.

Twilight Sparkle: I couldn't agree more, Cynder.

Percy: Wow.

Just then, Sharpfin came to see them with some news about the Ancent Terrasquid.

Sharpfin: There you are, Friends. As promised, I will personally be taking you all to the Twisty Tunnels, where I guarantee we will find the Ancient Terrasquid, safe and sound, without any trouble at all.

Flynn: And we're talking that impressive-looking ship of yours, right, Sharpy? Are you as fired up about this as I am, Tessa?

Tessa: The Chieftess said she needs my help in Woodburrow, so I'm not going this time.

Flynn: You guys want me to go talk to her...? Give her the ol' Flynn charm? I have a way with people you know.

Tessa: No, but thank you. Good luck, Flynn. I know you, our friends, and the Skylanders can do it!

Flynn: All right then! Let's go find that Terrasquid! Ready when you are, Gang.

Sunburst: Okay, let's hope we'd stop Kaos that way for sure.

Starlight Glimmer: And we'll make sure of it, Sunburst, together.

Fizzlepop Berrytwist: Well, why don't we?

Sunburst: Come on.

Starlight Glimmer: Let’s go.

So, they took off with Sharpfin on his ship for Twisty Tunnels.

Meanwhile at Kaos' Kastle, he was giving himself some space while seeking the Ancinet Terrasquid.

Kaos: Soon, Twilight, Thomas, SpongeBob, Mickey and Mumfie.
