While Toad got "acquainted" with the Piranha plants Waluigi gathered things he was fairly certain he would need: His mallet, a couple handfuls of pocket-sized Bob-ombs, some of his special insta-grow piranha plant seeds, and a wrench from his tool box. Once he was sure he was ready he left his house and made his way out of town. Waluigi gave a lot of thought to his first course of action and figured he may as well deal with the other usual suspect first: Bowser, the Koopa King. As Waluigi was exiting town he saw a group of Goombas that he was all too familiar with. They called themselves 'The Great Goomba Group' and they were just a bunch of little punks who always gave him a hard time, him and Wario, although Waluigi could've cared less the fact is they always messed up Wario's car so it came back on him anyway. Waluigi decided to get a little payback on those punks so he pulled out a bob-omb, wound it up, and chucked it at the Goomba group.

Goombash, the leader of the group, was leading them in harassing a young Goomba girl. "Come on cutie; let's go get a shroom shake together!" He said, trying to force her to come with him into town. "How many times do I have to tell you shell-heads that I'm not going anywhere with any of you!" She snapped, tossing back her purple braid. The Goomba goons chuckled. "You ain't gonna find a better Goomba guy than Goombash." One said. "Yeah, Goombash is the best!" Another added. Suddenly a little bob-omb landed in the middle of their huddle. "Hey what's this? Is it a toy?" one of the Goomba goons asked as he looked at the little bob-omb. "Oh shroom, that's a real bob-omb and it's gonna blow!" Goombash exclaimed as he looked at the little explosive as it began to blink red. The girl Goomba quickly ducked into a nearby bush for cover just seconds before the bob-omb exploded, sending Goombash and his goons flying in all different directions.

Waluigi watched as the Goomba punks went flying and laughed. "That's what you get you lousy punks! Wahahaha!" The Goomba girl pulled herself out of the bush and saw Waluigi. "Well I'll be a koopa's aunt; Waluigi threw that bob-omb." She said to herself. She walked over to Waluigi as his laughter was calming down. "Who are you?" He asked when he noticed the little purple Goomba girl standing in front of him. She looked up at him. "I'm Goombette, those idiots were pestering me and your bob-omb was the answer to my prayers." She said. "I was just getting my revenge on those little punks." Waluigi said. "Well whatever your reason you helped me, so I guess that means I owe you one." Goombette said. Waluigi thought about it for a moment. "What could you do or give me since you owe me, eh?" "How about you tell me what you're up to for starters, then we'll talk." Waluigi then explained his mission to Goombette. "Oh? Well then I have just the thing; my uncle Goomber works for Professor E. Gadd and he gave me some of the chain chomp orbs from the orb machines they made for the Mario Parties." Waluigi grinned; chain chomp orbs would be nice additions to his artillery. "I can also offer my help as well. I may not look it, and that little scene earlier wasn't exactly my best moment, but I am a pretty good fighter. I'm also pretty knowledgeable too." Waluigi pondered her offer for a moment, and then Goombash came waltzing up.

"I bet you think you're really something you beanpole! I'll make you pay for throwing that bob-omb!" Before Goombash could make good on his threat Goombette whipped out her hammer and smashed Goombash flat as a pancake. "Beat it you bum!" She snapped as the flattened Goombash ran off whimpering and threatening his revenge. "Say, you're pretty handy with that hammer." Waluigi remarked, actually a little impressed with the Goomba girl's spunk. "You bet I am. I can also use a boomerang too. So does that mean you'll accept my offer to help you?" Waluigi shrugged. "Do whatever you want, I need to get going." "Okay then. I'll go with you but if you want me to leave then just say the word and I'm history." Goombette said as the two started their journey to Koopaland."

"You stupid little Goomba brains! Can't you do anything right?" Wendy O. Koopa barked at her Koopa Troopa escorts as they tripped and dropped her bags of clothes and jewels she had just purchased in Koopa Town. Wendy O. Koopa was Bowser's daughter and she was daddy's little princess, which meant she got everything she wanted. She wore a big pink bow on top of her head that matched her pink spiked shell, a string of large pearls around her neck, large gold bracelets, and pink high heeled shoes. Wendy may have been a spoiled princess but she had no qualms with getting her hands dirty if she needed to and, in her own mind at least, was not only the toughest lady Koopa but the most beautiful too. (No one else believes that at all.) As Wendy was scolding her escorts her attention was drawn to the outsider that was walking past her. It was Waluigi, the taller, and more intelligent of the Wario Bros. and Wendy had to wonder what he was doing in town. Waluigi didn't normally work with her father and she hadn't heard of any new schemes either. Wendy decided to ask Waluigi what he was up to, walking around Koopa town.

Waluigi and Goombette were headed for Bowser's castle when a pink shelled Koopa stepped in front of them. "Why hello there, tall, dark, and…lanky. What brings you to these parts, hm?" Wendy asked flirtatiously. Goombette gagged a little. "Oh gosh, is she really flirting with you?" Wendy shot Goombette a look. "Shut your trap you little fungus!" Waluigi sighed. "Oh, brother. Look I don't got any business with you, I just wanna see Bowser." Wendy batted her eyelashes at Waluigi. "Sure thing sweet 'n' sour. I'll take you right to him." Wendy led Waluigi and Goombette to Bowser's castle. Along the way Waluigi crossed his fingers and prayed that he could leave quickly. "This is ridiculous! Mario and Luigi get beautiful princesses and even Wario gets Mona and what do I get? The lousy Koopa king's lousy daughter! This isn't fair!" He muttered under his breath.

When they arrived at Bowser's castle Wendy said that her father was in the throne room. Waluigi and Goombette marched right into the throne room. Bowser was contemplating his next evil plot when the door to his throne room flew open. He looked over and saw Waluigi and Goombette. "Whaddaya want?" He asked. "What did you do with the Mario Bros. and the Princesses?!" Goombette demanded. "And Fat-head." Waluigi added referring to Wario. Bowser looked at them blankly for a moment. "I don't know what you're talking about." He said. "Don't play dumb, they were gonna throw a Mario Party but they've all disappeared and their little toadstooge asked me for help." Waluigi explained, glaring at Bowser. "WHAT! They were throwing a Mario Party and they didn't invite ME!?" Bowser yelled angrily. Waluigi and Goombette just stared incredulously at the Koopa King for a moment, then Waluigi found his tongue. "What are you upset about that for? They never invite you; you always just crash the party." "That's beside the point! When you find them I'm gonna roast them all!" Bowser boomed. Goombette tugged on Waluigi's sleeve so he would bend down and she could whisper to him without Bowser hearing. "I don't think he did it." "Or maybe he's just a good actor?" Waluigi whispered back. They both looked at Bowser for a moment then shook their heads. "Nah." "I don't have a plot to capture anybody right now and I know that my Koopalings don't have any evil plots going right now either, so buzz off loser!" Bowser said, dismissing Waluigi.

"Wha? 'Loser'! I'll show you who's a loser shell for brains!" Waluigi barked at Bowser who just laughed. Just then Wendy walked in and Waluigi hit her with his mallet (Instead of the Koopa Troopa by the door that he was actually aiming for.) and she screamed and ducked into her shell as it went flying across the room. Wendy ricocheted off the walls a couple of times before colliding with her father's nose. "STIIIIRIKE!" Waluigi exclaimed as Wendy peeked out of her shell and saw her father's nose. "Oh, daddy, I'm SO sorry, it wasn't my fault I swear!" She whimpered, slowly inching toward the door. Waluigi laughed and exited the throne room with Goombette before Bowser could yell at him. "Ha! That was hysterical Waluigi!" Goombette said, laughing as they exited the castle.

Then they heard a voice behind them. "Just where do you think you're going honey mustard?" Waluigi shuttered as he turned around. "What?" "I heard you talking to my daddy. Not that I want to help those miserable little creeps but…" Waluigi braced himself. "But what?" "I want to get to know you better Waluigi, besides if I'm with you Daddy's minions won't be as much of a problem for you." Waluigi contemplated the idea. The pros were that her shell made a dandy weapon and she did have a point, Bowser's Koopa Troopas wouldn't attack his daughter. The con was that she had a crush on him so Waluigi would be fighting her off all the time. Pros did outweigh the cons. Waluigi sighed, knowing he would regret his decision later. "Okay fine. But you do as I say, got it?" Wendy practically jumped for joy. "You got it!" "Are you sure that it's a good idea to let her come along?" Goombette asked. "You saw how useful her shell is. Besides, if I say no she'll either follow me anyway or set all the Koopa Troopas on me." Waluigi replied. Goombette nodded, he had a point; daddy's little princess could be more problematic if they didn't indulge her just a little bit.

The now trio continued their journey away from Koopaland and to...parts unknown? "Where are we going cookie crumb?" Wendy asked, batting her eyelashes again. Waluigi shuttered a little. "I...I don't really know. Wah! I have no idea how to this 'hero' stuff!" He fumed, frustrated at having no idea where to go next. Bowser didn't kidnap Mario and the others and obviously Wario didn't do anything so then who else could have done it? "That's okay, we can just go wherever the mood takes us~" Wendy said flirtatiously. "King Boo. We should go to Forest Haunts and pay that big ball of hot air a visit." Goombette said, popping in between Waluigi and Wendy. "Who asked you, repulsive fungus?" Wendy said, turning up her nose. "Waluigi decides where we go, don't you?" Waluigi held back the urge to throw up and looked down at Goombette. "That's a good idea. Now that you mention it King Boo doesn't like Mario either." "So it's settled, on to Forest Haunts!" Goombette said as she started to walk. Waluigi followed Goombette and Wendy was right behind him.

"Oww... I think I chipped a tooth!" Wario whined, sticking a finger in his mouth to check. "Did you really think you could CHEW your way out?" Peach asked incredulously. "Yeah, I didn't think even YOU were that stupid Wario." Daisy added. "I don't see you creampuffs doing anything constructive so shut yer faces!" Wario snapped back. "We'll get out of here; we just need a plan... What about the ceiling?" Mario said thoughtfully. "If I can find a way to release the chain on my cage that'll be a start." He said, climbing the side of the cage, following the curve at the top until he was hanging upside down. He reached up and tugged on the chain, it gave a little!

"Yes! I think this might just work!" He exclaimed as he tugged on the chain even harder. Suddenly he heard a click, then a panel in the ceiling above the cage opened and a small cannon popped out. "Oh shroom..." He whispered just before it blew flames in his face. "Wahaha-ooo!" he cried as his face was scorched. Mario fell back onto the floor of the cage, the tip of the right side of his mustache still lit like a candle. "Hey bro, you okay?" Luigi was now really sure they were in serious trouble.
