"Wah," Wario greeted at Waluigi's Taco Stand in Seaside Hill.
"Wah," Waluigi greeted back, eating some of his tacos.
"Wah!" Toadette wailed as she was crying, running up to the taco stand at the Ribbon Road, sobbing. "I soiled my diaper!"
"Wah... whatever." Waluigi spoke up as he was making some new tacos.
"Do you ever say anything aside from 'wah'?" Dry Bowser asked Waluigi as they were both racing at the Bone Dry Dunes, with Waluigi chucking free tacos at the guests watching the race from the sidelines as a way to increase revenue and attention for his taco selling business.
"Wah... maybe if I feel like it, wah." Waluigi replied as he was managing to drive well while chucking tacos.
"Look, it's the Wah guy!" Petey Piranha laughed as he pointed at Waluigi and the taco stand on the sandy shore of the Gelato Beach near the yellow pier. "Everyone point at him and laugh!"
All the beach goers looked at Waluigi and laughed as they couldn't help but have pity, with Waluigi feeling insulted as he pulled out a slingshot and fired tacos at everyone, somehow knocking them out.
"I didn't say that tacos were only for eating," Waluigi remarked with a smirk as he folded his lanky arms together. "Wah."
