(the episode starts with Guido and Cera are Dairy Queen)

Cera: guess everything seems peaceful after dealing with Zarnot

Guido: now all I gotta do is to get people to see the painting

Dave (Yin Yang Yo): hey I'm looking for the Ninja Warriors,is this it?

Guido: You've come to the right people so how can I help you?

Dave (Yin Yang Yo): I have come to find someone that could decipher this (shows them a card)

Cera: It's a Ninja card,where did you get that?

Dave (Yin Yang Yo): in the woods why?

Cera: just asking

Guido: really you don't suppose…?

Cera: that the prehistoric beast want him to obtain it

Guido: I'm gonna gone crazy but that works too

Cera: anyway I'm gonna check out the woods to see that any other weird things happening in there (runs off)

Guido: yes you go do that

(cuts to Lina and Petrie)

Lina: if I was a ninja card where I would be hiding?

(suddenly Choboo shows up)

Lina (Yin Yang Yo): Well,well,well look who decided to show up,mind telling us what you're up to this time?

Choboo: I've just resurface monster island

Petrie: monster island ain't that the island that got sank years ago?

Choboo: yes,and that's not all it's the resting place for Meteor the Lariosauro

Lina (Yin Yang Yo): you mean the most powerful monster of the Night Fall? forget it man there's no way we're letting you

Petrie: yeah so give it up

Choobo: we'll see about that (disappeared)

Lina and Petrie: …

(cuts to Chomper and the others)

Chomper: dude they just sent Yang out front

Guido: he just wanna see something is up within the woods

Chomper: you'll never let me ride that motorcycle,and how come Cera and Littlefoot don't drive them?

Yin (Yin Yang Yo): (knocks his head) earth to Chomper because it'll be physically impossible for them to ride a motorcycle due to the fact that their 4 legged and they their claws aren't as flexible

Chomper: fair point

(cuts to Yang riding in the woods with his motorcycle)

Petrie: Yang!

Yang (Yin Yang Yo): huh?

(Petrie shows up)

Yang (Yin Yang Yo): Petrie what are you doing here?

Petrie: came to warn you that Monster Island has been resurfaced

Yang (Yin Yang Yo): wait (stops his motorcycle) what do you mean by resurface?

Petrie: because I'm sensing tons of dark energy,warn the others

(at the house)

Chomper: Monster Island you say?

Nanami Nono: it's a Island that existed years ago it's the operation base of Choobo we wanted to use the toxic to give the island more powerful

Ruby: Lina and Petrie must've noticed when Choobo told them his plan

Littlefoot: good that'll give us time

Cera: time for what?

Littlefoot: to decipher that card Lina and Dave obtain

Nanami Nono: oh you mean the Stegosaurus and Papa Sharptooth card,yes it'll give us enough time in case a Kaiju showed up

(at the fortress)

Lina (Yin Yang Yo): so this is the Night Fall fortress,talk about a fixer upper

Petrie: come on the dark energy is got to be here somewhere

Night Master: (snoozing)

(Lina and Petrie are sneaking in quietly until suddenly)

Night Master: (wakes up) surprise!

Petrie: Let's duel!

(battle scene)

Night Master: don't just stand there the captures

Choobo: (traps them in the cage)

Night Master: never sneak in without any precaution

(eyecatch)

Choobo: this is too easy

Night Master: well done Choobo you have managed to capture their friends and lure them to a trap

Choobo: now all I gotta do is to lure them to Monster Island and vanquish the Ninja Warriors forever

Yuck (Yin Yang Yo): you do realize that island has been sunken for like 30 years

Wendinu: not until now,especially since Lariosauro has arisen

Carl the evil cockroach: oh this is too good the most powerful Kaiju under Night Fall's forces

Choobo: ok Slimy just like we planned

(back to Guido at Burger King)

Guido: So got any updates on the toxic waste thing?

Littlefoot: no but I do heard that Island has risen up recently

Ruby: I wonder if this has something to do with the toxic waste thing

Yang (Yin Yang Yo): beats me

Chomper: So have Lina and Petrie told you more about Monster Island?

Cera: no they haven't send back a email

Ruby: that is strange they've should've come back by now
