Lita and Sunny run into some childhood bullies, Frank a mutant goat, and Kyle a mutant tapaer. The two have signed up for a karaoke contest and mock that Lita that she can't sing. So Sunny, against Lita's protest, signs the two of them up for the contest as well and proclaims to the bullies that they'll win it. And the two just laugh her off.

So when the girls relay their problem to all their friends, two of them, Jay and Andre, take them to their old, slightly eccentric, vocal coach who helps the girls hone in their singing. And they practice a song and sound great, unaware Frank and Kyle are spying on them.

When Lita and Sunny go on, the bullies try to sabotage their performance only to get caught by Zink and Shadow who then attack them.

[Lita]

I can feel you comin' from a mile away

My pulse starts racing from the words that you say

[Lita and Sunny]

And you say so many of them like you don't have a clue

That I'm signed, sealed delivered with a stamp on

… You don't have to try too hard

You already have my heart

You don't got a thing to prove

I'm already into you

So
… Hold, Hold, Hold, hold me tight now

Cause I'm so, so good to go

Don't say Don't say good night you know

You had me @ hello

You had me @ hello

You had me @ hello

Don't say don't say good night you know

You had me @ hello

Toward the end of their song, the bullies are knocked toward the girls who kick them off the stage. The crowd loves their performance and their named the winner's.
