Sonic the Hedgehog was speeding by Mystic Ruins, when he saw Tails' workshop. He went to the door.
Sonic: Hello?
No answer. He knocked again as Tails was approaching him from behind.
Tails: Hi Sonic!
Sonic: AAAAAAA! Tails! Don't do that!
Tails: Sorry, Sonic. I was in Station Square checking out my enemy tracker.
Sonic: You have an enemy tracker?
Tails: Yup! Wanna see?
Sonic: Ok!
So Sonic looked at the enemy tracker, and something amazed him.
Sonic: Who is tha… MARIO!
Tails: What is he doing is Station Square? Sonic, will you…
But Tails was too late, because Sonic had already hopped on a train to Station Square to stop Mario.
