Waluigi was at Peach's Birthday Cake, trying his best at selling tacos in the sweet, sweets based board, with there being plenty of cake figurines featuring several classic characters.
"Wah, I wonder why there are Piranha Plants and Goombas here." Waluigi remarked as he was situated in the middle of the pink colored cake, looking all around as he stretched his arms. "Oh well, so long as I get business."
"...So let me get this straight." The Goomba near the yellow ladder and Bowser's small cake stated as he waddled up to the top of the cake, facing Waluigi. "You're selling tacos on a giant cake?"
"Basically, yes." Waluigi stated as he held a chicken flavored taco in his right hand. "I figure that chumps like you wouldn't mind, considering how you're here all the time."
"...Chumps, eh?" The Goomba spat back as he shook his head, heading back to his position. "Well you just lost a sale. Congrats, skinny legs!"
Waluigi sighed as he shook his head, munching the taco he was holding as he folded his arms together. "Meh, I always have the Piranha Plants."
And then four Piranha Plants surrounded Waluigi, munching down on him as he screamed in pain.
"Hey, Wally Ally!" Toadette exclaimed as she waved her right hand to Waluigi, who looked completely injured as he had returned to Seaside Hill. "Where were you?"
"I was at that stupid birthday cake that Peach owns." Waluigi grumbled as he collapsed on one of the piles of tacos, too wounded to feel anything. "That place looks innocent, but don't let it fool you. those plants will eat you alive."
Petey Piranha mumbled as he sat at one of the wooden tables with Dry Bowser, who simply shrugged as Toadette tried her best to heal Waluigi's severe wounds.
