Waluigi screamed due to the fact that he was being chased by a giant boulder in the depths of Wario's Gold Mine, chucking his various sporting equipment back at it while panting. A certain speedy blue hedgehog dashed by since he was doing a Sonic Dash and happened to notice the action going on.
"Need any help tall legs?"
"Wah... you're gonna have to do better than that!" Waluigi taunted for suddenly he bumped into a gold filled mine cart, falling into the gorge below him and screamed.
Sonic laughed for he felt that this situation was quite hilarious, with him suddenly being hit by a mine cart as well. "Guess I should have looked while I was ahead!"
This of course led to both Waluigi and Sonic fighting off the array of mine carts that were being summoned around them with it getting to the point that they ended up breaking the entire thing apart.
