Mario and Yoshi arrive at Peach’s castle and arrange a meeting with Peach, Luigi, and Toad.
Mario: This is what we found in Bowser’s Castle: a prisoner!
He shows Billy to everyone.
Luigi: Uh, are you sure that thing is a Yoshi?
Yoshi: What you mean?
Toad: Have you even looked at him yet?
Mario: Uh, no. I’ll check.
He looks at Billy.
Mario: How did I miss that?
Yoshi: Miss what?
Mario: That freckle on his face.
All but Mario: …
Mario: Just joking. But what’s with the shell on his back?
Yoshi: And the spikes?
Peach: Maybe they’re glued on!
All but Peach: …
Toad: Peach, leave.
Peach leave.
Toad: Maybe he’s a mutant?
Mario: Or maybe Ludwig was right…
Toad and Luigi: ?
Mario: Ludwig said that Billy was his child and that he had a wife, and when I told him that Bowser said to take Billy as far away as possible from the castle, which did happen, he said Bowser WANTED me to think that.
Luigi: Not the most obscure idea…
Everyone looks at Luigi.
Luigi: Something had to happen a long time ago with Bowser; otherwise the Koopalings would not exist. Maybe the same thing is happening with Ludwig.
Toad: Then why is it a Yoshi baby?
Luigi: Different species can have affection for each other.
Toad: So you’re saying Ludwig’s wife is a Yoshi?
Luigi: Something like that.
Mario: I feel bad now. When he told me he was married, I said “Ha! Who could love you?” He seemed very insulted.
Luigi: How rude.
Mario: I’ll take Billy back. That’s the least I could do.
Yoshi: Oh no you don’t! Why would you believe Ludwig’s story? How crazy! I’m taking Billy and teaching him how to be a Yoshi!
Toad: No, wait!
Yoshi runs away with Billy.
Toad: Great.
Mario: Don’t worry. Luigi, try to get Billy back from Yoshi. I’ll go find Ludwig, and Toad, come with me.
Toad: Why me?
Meanwhile, Ludwig, Larry, and Iggy are in the forest, traveling to Mario’s house.
Iggy: Can’t… go… any… further…
Larry: We haven’t been walking THAT long.
Iggy: Feels like a lifetime!
Mario and Toad appear out of nowhere.
Mario: Ah! There you are!
Larry: What are you doing here?
Mario: We have found out that you were telling the truth, and I apologize for taking Billy and insulting you.
Ludwig: Thanks. I accept your apology.
Larry: Wait, where’s Billy?
Toad: That’s the problem.
Mario: Yoshi has taken him; he doesn’t believe your story.
Iggy: How do we get him back? Yoshi’s the fastest Yoshi in all of Mexico!
All but Iggy: …
Iggy: What?
???: You’re dead, that’s what!
Lemmy, Roy, and Morton appear out of nowhere.
Lemmy: Traitors!
Morton: This is your funeral!
Roy: Prepare to fight!
Mario: I can defeat you with one hand behind my back!
Iggy: I have a better idea.
He throws the boomerang Mario threw at him earlier, and it knocks the trio out.
Toad: Smart.
Meanwhile, Luigi is trying to get Billy from Yoshi.
Luigi: Dynamite will help me get him back!
Luigi throws a stick of dynamite at Yoshi. Unfortunately, it hits a cactus (Where did the cactus come from?) and bounces back at Luigi.
Luigi: Ack!
Boom. The explosion knocks Luigi off a cliff.
Luigi: Ouch. This should do the trick!
He rolls a giant boulder to the edge of a cliff 20 feet above Yoshi. Meanwhile Yoshi is teaching Billy something.
Yoshi: Ok, this is most coveted technique that Yoshi can possess: the flutter kick. You jump in air, and then rapidly kick in air.
Billy: I miss Daddy.
Yoshi: I’M your daddy now! Bwa ha ha ha!
Billy: …
Yoshi: Now you try it on green thing up there.
Luigi: Oh no…
Billy easily makes it up to Luigi with his flutter jump, and then expertly kicks Luigi.
Luigi: Ack!
After 10 minutes of non-stop torture, Billy falls back to Yoshi.
Yoshi: Wow! You the master!
Luigi, dazed, falls off the cliff. And then the boulder squishes him.
Luigi: Ouch.
The ground underneath him breaks, and he falls down 100 feet before being squashed by the boulder again.
Luigi: I think I’m being cursed by the Americans.
Luigi sees Yoshi across a valley.
Luigi: I’ll long jump!
It doesn’t work, and he falls down 50 feet. (Luigi must hate Americans by now.)
Luigi: I don’t hate Americans, I hate their distances. Try Canadian!
Fine. The ground falls underneath Luigi and he falls 50,000 meters.
Luigi: This stinks. Huh?
He sees Billy right beside him.
Luigi: Lucky me!
Guess what? Say hi to your best friend: ground! He’s 10,000 meters below you!
Luigi: …
The ground underneath Luigi breaks, and he falls 10,000 meters… into a pit of spikes.
Luigi: Yow!
Luigi flies all the way back up to where he threw his dynamite.
Luigi: Wow. That was intense. Well, time to try again.
Yeah, right. You know what will happen if you do that.
Luigi envisions falling off a cliff.
Luigi: Well, time to give up.
Back in the forest…
Mario: I’d like to have my boomerang back.
Iggy: Never!
Larry: Anyway, now what?
Mario: I’ll see if Luigi has captured Billy from Yoshi. You guys, follow behind.
Ludwig: Okay.
The five of them leave, when Lemmy wakes up and takes out a cell phone.
Lemmy: Bowser! The plan failed! We need another plan!
Bowser: Don’t worry, I know what to do.
