"It isn't!! It's like nothing I've ever seen before!!"

For Mario, that's a rare occurence, so he's extra enthusiastic right now.

He seems perfectly comfortable hanging where he is, also. Though with his arm hooked securely, elbow bent, hand gripping his overalls, maybe he is fine.

"Trains? Over land? Sure." Mario is obviously a bit distracted. Even the roaring clap of thunder that makes him wait to speak doesn't seem to faze him. "If warp pipes aren't an option, anyway. But I love a good train."
