Gumball and Darwin Watterson vs Robot and Monster
Your rhymes are sour, though your name tastes sweet
you will both taste defeat
I'll cook you both up and turn you into
I'm usually a nice guy but don't get me wrong,
But you two will die by the end of this song!
You can never beat us, we will kick your ass in polo!
Not trying to be mean but are you two homo?
You're rhymes suck so bad, they make us wanna barf!
I'll stomp on you in the end and feed you to Marf!
