Berserk

"Berserk" is an instrumental song that plays on the radio of the tank Stacy is driving in "Ex-Treme Troubles". Stacy is singing along with the music, thus providing the lyrics. The name of it probably comes from the Berserk Button trope, which is used here with Stacy.

Stacy: I'm ridin through the streets in my giant tank!

I'm really hoppin mad right now, so you boys better watch out!

I'm huntin you down, and when I find you,

I'm gonna run you out of town!

YEAH!
