Gamble Game Gallery

While Mario, Luigi, Yoshi, and Toad were collecting stars inside the Big Beast's Belly, Wario and Waluigi entered Gamble Game Gallery. It was a large casino that resembled Casinopolis from Sonic Adventure, but instead of only slot machines, there were also huge chips of different colors all piled up to make platforms. And much like Casinopolis, there were doors leading to various minigames.

Waluigi: Wahahahaha! We've found the pot at the end of the rainbow!

Wario: As much as I wanna make this place all mine, we'll still have to search for some stupid stars to save this moon and our planet.

Waluigi: Oh yeah… Wah…

Star #1: Scale the Casino

The Wario bros see the star at the very top of the casino.

Wario: Alright Waluigi, you're gonna have to give me a boost, because my jumps are low.

Waluigi: WAAAAAAHT?! You're fat, and I'm skinny! You'll crush my bones! I've got a better idea. Hold on to me!

Wario grabs on as Waluigi takes out his magnet. He uses it to get both of them to a higher level of the tent. Then, both of them walk across a beam to get to a rope that takes them to the third level. Finally, both of them scaled one of the iron bars holding the tent up to get the star.

Star #2: Mystery of the Mice

One of the Piantas was funming while jumping up and down like a madman. The bros came to check him out.

Wario: What got you so worked up?

Pianta: Those mice! They stole some of my food and coins that fell down! They went somewhere into the bathroom, but I can't make out where they disappeared to…

Waluigi: Hmm… Alright, we'll help you with your mess, but it's gonna cost ya!

Pianta: Well, I saw those mice steal a Power Star as well. I don't need it, so that can be your payment.

Wario: Deal.

Both bros walked into the bathroom to check. One of the toilets was opened, so that means one thing… they had to jump inside.

Wario jumped in first, but got stuck because of his large physique.

Wario: HUUUUUURGH!

Waluigi just facepalmed and pushed Wario down with his legs before going down himself.

Sewers

The bros now had to go through a maze with many mice holes in the walls and the waters in the sewers that would be harmful to the dastardly duo. They just had to navigate through the maze and go into a small opening in one of the walls to get to the star.

However, the nice in particular, were VERY annoying. They'd constantly home in on the bros and trip them over. One of them even stole Waluigi's cap before Wario beat the living heck out of them. Once they got through, the Star was waiting for them atop those stairs.

Waluigi: Stupid mice… This casino owes us big time for this job.

Wario: Yeah. After this is all over, we're so buying this place.

They grabbed the star and went back to the casino.

Star #3: Crazy Roulette

Wario: Now that we're back, let's-a try out some of the games. See if we can win big.

Waluigi: With you there!

The two walked around and saw a group of Piantas playing a roulette minigame. One of them looked dissatisfied.

Pianta: These people think, this kind of roulette is fun. They must have never played real Roulette! Do you want to see the REAL roulette? I'll give you one of my entrance cards for it!

The two looked at each other and grinned evilly.

Wario: Give is the card!

The Pianta obliges and the door to the roulette minigame opened. Before they walked inside, they overheard another Pianta talking.

Pianta: I've bet everything I have on 26! I practically can't lose. I have a system that's never failed so far! And it already worked once before, so what are the chances it's gonna fail now?

The two smiled wickedly again.

Wario: Let's totally one-up him and take his bet!

Waluigi: Wahaha!

Both walk in and find themselves shrunken in a giant red and black roulette going all the way downwards making a spiral. The numbers went all the way from 1 to 36

Waluigi: So we're the balls? Interesting.

Wario: Remember. 26.

The two slid down on the Roulette. Not only would this win them big, but it was also fun! When they got to 26, they ground pounded on the number, and the Star appeared at the bottom of the slide. They slid down and claimed it.

Star #4: Mischief Masher

Pianta: Hey, are you new to the casino? Want to know my favorite game? Mischief Masher! You should give it a try. Here I know, I'll give you one of my entrance passes. You'll love it! You get one try, make it a good one!

The Pianta gave the bros the entrance pass and it opened the door to the Mischief Masher minigame.

Wario: Mischief, eh?

Waluigi: Sounds like the best game ever!

Both walk in. The minigame was an enemy hoard where the bros has to defeat every enemy without any way to heal themselves. These enemies included Goombas, Chuckyas, Pokeys, Fly Guys, Mice, Spiny Piranha Plants and a Bandit. With every enemy defeated thanks to Wario's strength and Waluigi's crazy fighting skills, the star appeared.

Star #5: Catch the Thief

Pianta #1: STOP! THIEF!

A bandit had stolen some coins and a star from the casino. The Piantas were going crazy over it.

Pianta #2: That thief! He stole money from everyone here! And then he ran off!

Pianta #3: Hey! You two! Do you think you could help us? This bandit from up there is way too fast and nimble for us. If only there was a crazy athletic plumber that could help us catch him…

Waluigi: Crazy? Athletic? WAHAHAHAHAHAHAHA! Leave this one to me, bro.

Wario: Whatever you say.

Waluigi gets to the same spot where he went to get the first Star and sees the Bandit on the opposite side. Running as fast as he could, he chases after the Bandit for a little while until he finally catches him.

Bandit: Hey! What are you-?!

Waluigi: Give me the Star, and my money! Nobody thieves around here except me and my brother!

Bandit: Okay…you win. I'll return the gold to the Piantas and I'll give you this.

The Bandit takes the Star out of his bag and Waluigi takes it.

Waluigi: WAHAHAHAHAHAHAHA! Waluigi number one!
