Here is how Code Red introduces Team Natsu and the Apocalyptic Duo to the Autobot Base and a new adventure goes in Crash, Thomas, and Ryan meet Moana 2 weeks later.
(we then see the rock hiding the Autobot base)
(we then see the Red Ship flying through the air)
[it lands on top of the rock]
Ryan F-Freeman: Welcome to the Autobot base.
Natsu Dragneel:(looks around) There's nothing here.
Nighlock: A perfect deception for the enemy.
[he leads them to the elevator as Malfunction takes the Autobot Elevator]
Ryan F-Freeman: And here... we... are.
[the elevator opens up]
[Code Red, Ryan, Team Natsu, and the Apocalyptic Duo step out and see the Autobots]
Evil Ryan: Hey, guys, we're back!
[the Autobots turn to them as Malfunction finally arrives]
Crash Bandicoot: I guess Megatron is not in Siam when we saw Anna.
Jack Darby: [off screen] He's busy at the moment.
Ryan F-Freeman: Ok. If you had something. I needed that.
Ratchet: You're a little late for that part, Ryan.(points at Miko) She already did that.
Miko Nakadai:(ignores him)
Erza Scarlet: I don't approve of there being children here.
Nighlock: We either blame Miko or Wade for it.
Miko Nakadai and Deadpool: Hey!
Nighlock: It's true.
Major Malfunction:(to Optimus) So, where is the Big M?
Optimus Prime: Out looking for portals for more adventures. It's been very quiet, the boringness of the silence got to him.
Happy: Who's Megatron?
Flash Fire: Long story.
Crash Fire: Not easy to explain.
Flash Fire: Was evil.
Crash Fire: But now...
Flash Fire and Crash Fire: He's reformed.
Nighlock:(teasingly) You know, it's really cute how you two finish each other's sentences. Just like FitzSimmons.
(suddenly, the computers blink, signifying they have a message)
Ratchet:(checks it) Megatron is reporting.
Optimus Prime: Put him through.
(Doctor Crash appears on screen]
Nighlock: So, Doctor, where's Megatron?
Doctor Crash: He's on his way now.
[The TARDIS appears and Doctor Crash comes out with a tiny Megatron]
Doctor Crash: Sorry he can't fit in my TARDIS. So. I use my shrink gun to make him the size of a mini Cody from Total Drama.
Ant-Man (Scott Lang):(uses one of his blue disks to return Megatron to normal size)
Ryan Tokisaki: Thanks, Scott.
(Megatron walks up to Optimus and holds out a book)
Megatron: I found this in some ancient ruins in Hawaii.
Doctor Crash: It was me who found it.
Megatron: Oh. Doctor Crash found this.
Ryan F-Freeman: Hawaii? Where Lilo and Stitch are?
Ryan Tokisaki: Let me see. [Looks at a book] Hmmm. It appears to be a key to the portals to other worlds. Including this one, Odette's world, Okoto, Cybertron and a bunch of others we don't need to mention.
Matau T. Monkey: I think we could sail on the seas. [looks at the camera] Umarak is not in this film. Right?
Deadpool: Nope. He not is in it. For once, I had nothing to do with it.
Nighlock:(uses his powers to activate the portal)
Matau T. Monkey: Madam?
Shadowcat: Thank you.
Nighlock: Wait. She's not doing that.
Ryan F-Freeman: Wait a sec. Rule number 1..
[Deadpool was about to answer then Kuryan stops him]
Ryan Tokisaki: Hold on. Come on, Nighlock. You got to remember.
Sci-Ryan: Always listen to Ryan.
Nighlock:(rolls his eyes)
(they then head inside the portal as everything goes black)
