The rocket had landed on the moon. Toad was the first to step out.
Toad: That's one small step for Toad,
Waluigi jumped out next.
Waluigi: One giant leap for WAAAAAAAAAALUIGI!
Yoshi: Ooh! I can't believe we're on the moon!
Luigi: So… how are we breathing without spacesuits?
Mario: I don't know. I guess it has an atmosphere. Now, we've gotta hurry because it won't be long before the moon reaches Earth's atmosphere.
Yoshi: He's right. Let's take care of these last courses and then stop Rashay.
Wario and Waluigi weren't paying attention, however. They were distracted by the sight of an entrance to a casino and grew dollar signs on their eyes.
Waluigi: There's a casino on the MOON?!
Wario: Jackpot, baby!
Luigi: Uh… guys?
The dastardly duo ran right into the casino.
Toad: There they go again…
Mario: On the bright side, they might find stars in there while we search for stars elsewhere.
Toad: So where should we search?
Yoshi: How about in that cave over there?
Mario and friends walked over to the nearest entrance which looked like a cave. But something didn't feel right about it.
Luigi: I… I… don't know…
Mario: Welp, we're not gonna get the stars just standing here. Let's a go!
The four walked in. Little did they know that the "cave" they walked in was actually a living creature and it opened its eyes.
Big Beast's Belly
The course looked identical to Inside Jabu-Jabu's Belly from The Legend of Zelda: Ocarina of Time, sharing the same interior textures. Below the hole leading to its stomach, there was a large not-so-deep pool of acid with many weird things in it, mainly opened treasure chests, a dead Gooper Blooper, a giant fish's skull and spines, half of a ship and many golden coins. The three felt like throwing up upon seeing the interior. Luigi's cheeks turned almost as green as his clothes. The smell was unbearably bad.
Luigi: Nope! I *gulp* want out!
Toad: Blegh!
Yoshi: If I knew this was the inside of a body, I would've brought a gas mask.
Mario: Let's just find the stars, *gulp* quickly!
Star #1: Bunny in a Belly
Mario and Co. defeated a blooper that tried to swat at them, then walked down to the stomach area.
?: Help! Help!
Luigi: Who's there?
The heroes looked around, Toad spotted a bunny who was trapped in a cell made of organ tissue.
Toad: How'd you get in there, little fella?
Bunny: Oh, thank goodness! Did you guys get eaten by this… thing too? I was chasing after this star that fell out of the sky, but got trapped in here. Can you help me out? I think there's a switch around here somewhere that can free me.
Yoshi: Sure thing!
Yoshi looks around and flutter jumps up to a ledge where he finds a purple switch. He steps on it, and the bunny is freed.
Bunny: Woohoo! Thanks dudes, I was super scared over here! Here, take this, if I hadn't chased after this, I would have never ended up in that situation.
The bunny takes out the star.
Mario: You're welcome! Be careful where you wander off to next time.
They take the star and are teleported back to the start.
Star #2: Twist up the Food Chain
Toad: Look!
The star was actually right above their heads, next to the beast's uvula. But it was too out of reach for even Luigi's high jumps to reach it.
Luigi: you're kidding me, right? They must be teasing us at this point.
Mario: Maybe we could try raising the acid levels by hitting the uvula. That way, we could reach the star.
Yoshi: In that case. Yoshi, ate the blooper nearby and aimed it egg at the uvula to rise the acid levels. When they did however, a shark came and attacked them.
All: AAAAAAAAAAAAAAAHHHHH!
The shark mauled them for a bit before the acid levels sank again.
Luigi: You've gotta be kidding me…
Mario: Oh, that's it! I'm gonna go down there, and give that shark a piece of my mind!
Toad and Yoshi: NO!
Mario didn't listen and went down. The others pursued him out of fear. But surprisingly found that same shark lied on the acid, jumping like a fish.
Toad: Ha! Serves it right!
Mario however looked concerned.
Mario: Um… I know you just attacked us earlier, but… Are you okay?
Shark: Can you lend me a helping hand? I have…uhm…infiltrated this beast! That's right, a proud shark like me would never get eaten by something as stupid and slow as this thing! But I'm kinda being digested over here. Can you help a pal out and drag me out of this acid?
Mario: You got it.
Luigi: WHAT?! Are you crazy?! That shark tried to KILL us!
Mario: Luigi, it's a wild animal who was just following it's natural instincts! It doesn't deserve to die for just trying to survive! Now help me pull it out of the water.
Luigi: Well, I guess if it stops attacking us, I'll help it.
Toad: I guess you're right.
The quartet pulled the shark out of the acid. Once it was far away from it, he thanked Mario and friends.
Shark: Good work, dude! You've all just earned a special place in the food chain!
Luigi: So, you won't try to eat us?
Shark: Nope!
Luigi: Phew, thanks!
Shark: No. Thank you!
Mario: You're welcome!
With that done, the heroes walked back up and hit the uvula again. This time, they were able to get to the star, safely.
Star #3: The Lonely Fisherman
The heroes next went into a maze filled with puddles of acid. They followed a long rope which stemmed to lead to something. At the end of the rope, they were surprised to find a Toad with a campsite, fishing rod, and beer.
Toad: Woah! People live down here?
Fisherman: Visitors? In here? You must be the first people I've met in years! You're looking for stars? Well, search no longer, I have something for you!
The Fisherman happily hands them a star.
Mario: Thanks! How long have you been in here, anyways?
Fisherman: No idea. I just assumed it's been years because of my long beard.
Luigi: Want us to help you get out of here? We know a way out.
The fisherman grew excited.
Fisherman: YES! YES! PLEASE! I wanna see the outside world again!
Mario: Let's a go!
They touch the star and all leave the beast's body.
