A FEW MONTHS LATER:
During an anniversary trip to a waterpark, Peter dismisses everyone to meet pack later in the day, Peter tries a waterslide, but discovers no actual slide. He is given a 'Starburst' candy, but after an initial sensation of riding a fruit wave, he finds himself smacked onto the pavement with a head wound. He realizes that the attendant had given him acid. When he is offered Skittles, he questions if it is also acid which the attendant confirms, being an adult working in a waterpark.
Meg fails to heed instructions to not slide headfirst and wait until the attendant at another waterslide gives clearance, and ends up with her head through Brian's rectum and visible through his mouth. Chris steals a Hispanic girl named Isabella's top, but when she calls him on it, he finds her attractive and Sally convinces him to get a date with her. The family, especially Lois, has some reservations about her when they find out that she already has two twin infant boys, but let it go on anyway.
Late at night after their date, Isabella returns to Chris and informs him that she is being deported, but plans to return quickly. Chris volunteers to watch her children until she returns.
Lois has major reservations about Chris' ability to care for two children and her concerns are well founded as he struggles to feed and care for them, but Brian convinces her to let him, or else Chris would never forgive her for not believing in him.
When Consuela, who is Isabella's aunt, brings news that Isabella can't return to the United States. Lois demands that they take the babies back to her, despite Chris's protesting at first, the family taking Dash and Sally also with them.
On arrival in Mexico, they find Isabella in a crime-ridden village and returns the babies to her but Chris convinces her to bring her with them to America as he doesn't believe this is a good neighbourhood for them, Lois agreeing that as a mother she can't leave them here.
The Smiths meanwhile have another trip only for it to again reveal to be the goo, this time by Hayley, while she and Jeff try to figure out how to put together a sex swing.
Pinkie in particular seems angry and calls Hayley a traitor but Hayley barely reacts saying she wanted to go to Rome so she sent her to Rome.
"You're missing the point. All I wanted was to have dinner once in a while, and spend some real time together!" Francine cried angrily.
"But you know what? I'm done. Done. And you know why? Because you are an ass family. If someone asked me who lived in this house, I'd say the Asses. And I'd be right. I just... I don't know why it has to... I..." Francine suddenly breaks down, sobbing onto the couch, Pinkie goes to comfort her and the others actually look remorseful, except Jeff who has no idea what's going on.
Turns out Francine spent the rest of the day curled up in her bed, and Stan actually gets rid of the goo in guilt.
Stan: Francine, you were right. We've been horrible. But we're gonna make it up to you. We booked a cruise. We leave in an hour.
Francine: You're just gonna put me in the goo.
Stan: No, we're not. Honey, look. I'm returning the goo chambers to the CIA.
Francine: Oh my God. We are going on a real vacation?!
Pinkie: Sure are.
Stan: The only goo you're gonna see is goo-od times. It was a stretch, but I made it work, didn't I?
The others: No.
Stan (proudly) Yeah I did.
Peter calls Glenn to come get them all in a plane and he flies down, Dash warning Sally Glenn will say many things to her, and all will be disguesting.
Quaqmire: Hey, you must be Isabella. I came as soon as I heard about you. And then I got on my plane. (CHUCKLES) Al-right.
"Come on man, if your gonna make sex jokes least make them actually funny." Sally snarked, more unimpressed than anything else.
Almost immediately though they are highjacked by dirty cops who steal there plane and Peter's van and have to walk.
Dash: God this heat.
Chris: Well maybe not wear a fuckin' beanie, dumb bitch.
Dash: Don't test me blondie, I will shiv you with a toothpick.
Meg: Uh guys.. Cayotes.
Chris allows himself to be severely bitten to save the babies, however Dash pulls out a pistol and shoots the one on him and scare the others.
"What the- You had a gun?!" Sally cried.
"Coarse, it was in my check in bag." Dash replied, putting the pistol back in her back jeans.
"Why didn't yo..."
"Sal they had assault rifles. I ain't dying in Mexico."
"Oh my god! I've been bite!" Chris cried fearfully, Isabella runs over bandaging him.
Lois: Oh my god Peter we did nothing, we're his parents and we did nothing.
Peter immediately changes the subject by saying how impressive it was seeing Chris protect the babies.
With lack of any better alternatives, they end up cooking the dead coyote at a night fire. Chris complaining about still being thirsty.
"Yeah, I'm so thirsty I'd be willing to drink anyone's pee.. Not you Chris, or Peter, but you know.. Anyone." Glenn insisted.
"Great, the coyote probably has some, drink up." Dash snarked back.
"... I don't need to drink anything." Glenn said back.
Suddenly a car pulls up and it turns out to be CJ who saved them instead. "Carl!" Sally cried, immediately hugging him.
"I followed your phone.. You're recommend-ably easy to track Sal, may wanna work on that." CJ replied, Sally does look at though her phone nervously in response.
"Oh, well, this is great. Can you help us get to the border?" Lois asked excitedly.
"Oh, you already in United States. this Texas." CJ revealed.
"What? S-So, wait, so we walked right across the border and didn't even know it? That is a problem. Not trying to be racist, but that is a problem." Glenn cried out, Dash admitting that he's probably right.
