The Warp Zone/Hidden Bridge

On level nine there is a warp zone
And if you enter it you'll have to walk alone
What looks like lava is actually a hidden bridge
So walk over yeah walk over it

Don't be sad
Don't be sad
Don't be sad
Don't be sad

Sometimes the radio plays to no one
Sometimes the radio plays to everyone at once
Tonight I'll be singing along
Sometimes the radio plays to no one
Sometimes the radio plays to everyone at once
So tonight I'll be singing along

So don't be sad
Don't be sad
Don't be sad
Don't be sad
