Lyrics (they start at 0:12):
Come on heroes let's meke evil fail!
With our might evil shall not prevail!!
They are all too dumb!
Let our power make them numb!
Evil is not as great as good
let's beat up those n00bs!!
They took over the radio...
But they are nothing but lame-os!
If we gather together and then fight...
Soon evil WILL JUST DIE!!
Come on everyone, let's beat eShroom Corp
Everyone knows this thing SUCKS A LOT!
eShroom Corp thinks that beat them up is impossible
But the power of the good side is just UNSTOPPABLE!!!
Come on let's prove those evils that good will win
And "winner" is a thing that evil will never be!
Let's prove that those fools are just wrong
And so those freakin' idiots will BE GONE!
Happy is greater than sad, everyone knows, it's a fact
Evil will lose to us VERY BAD!
They don't to admict defeat
Let's stomp those maggots with our justice feet!
Evil will soon fall because we're great... AND THEY SMALL!!!
