We're the Sonic Underground
From the Episode "Healer"


Come in, My Friend
Welcome to the party!
But only if your one of our kind!
The Adventure of our lives is now Starting
Robotnik's Empire Running out of time

We're the Sonic Underground
Listen to our Freedom sound!

Hiding in the heart of the city
We plot and Plan Robotnik's over throw
It's a dirty job and, no, It's not pretty!
Always on the run, Always lying low!

We're the Sonic Underground
Listen to our Freedom sound!
Never know where we'll be found
We're the Sonic Underground
