Lemmy Koopa was at Grumble Volcano, having decided to expand his tire service to more remote race tracks throughout the land.
"Hey, Lemster!" Morton yelled. "Wat'cha doing here? There's construction to be done here! By me!"
"Oh hi Mort! I'm going to sell tires here!" Lemmy stated.
"Yeah, well I'm going to work on some construction here! So beat it." Morton told him, pulling a hard hat out of nowhere and putting it on.
"I have some tires that will help other racers get by, despite your construction!" Lemmy told him.
"You and your lame excuses!" Morton ranted. "Now, beat it!" Morton pushed Lemmy aside.
"Fine!" Lemmy claimed, angered by Roy's obnoxiousness as he walked away.
Several minutes later, while Roy was jack hammering the ground, which only caused it to collapse into the lava, Lemmy went by on a Badwagon Kart with Monster Tires, rolling over Morton and the construction signs, crushing him.
"I am going to sell tires here, and now you can't do anything about it, Morty!" Lemmy teased.
Dry Bowser suddenly came down out of nowhere. "No you're not! This is my turf! And my turf is for me and my undead friends to relax, not for you to drum up business!"
"Oh come on!" Lemmy pouted. "You're the undead version of our father! Have mercy on me!"
"I will not let you turn my volcano into the next Seaside Hill!" Dry Bowser stated, crossing his bony arms. "Now get the fiery hell out!"
Lemmy momentarily stared at Dry Bowser. "Wow. You are heartless in more ways than one!" he told him. "No wonder you didn't make it to Mario Kart 7 or 8!" With that, Lemmy rode his Monster Badwagon away, leaving Dry Bowser and a flattened Morton behind him.
"At least part of my head made a cameo in the Bone-Dry Dunes!" Dry Bowser uttered.
