♪Come in my friend, welcome to the party
But only if your one of our kind
The adventure of our life 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 overthrow
It's a dirty job and, no, it's not pretty
Always on the run, always laying low

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