At the Diaz Household, Star was relaxing on the couch when Marco arrived and asked, "Um, Star, sorry for the vulgar question, but are...um...are the pink stuff in your chest...heart-shapped?"
"You mean my-"
Marco could only nod as he flushed. Star, in response, simply crossed her arms and gave the boy an annoyed scowl. "That is singlehandedlyy one of the stupidest things I've ever heard." she stated, surprising the guy, "Mewman biology might be different than human biology, but it's not THAT different."
"It isn't?" Marco asked.
Star simply let out a disappointed sigh and told the boy, "I suggest you actually bother to see a male and female mewman naked before you make assumptions of their body parts." she scolded, right before asking, "Speaking of which, why are you asking me that in the first place?"
"Janna asked me the same thing, and I started to wonder myself-"
Hearing such a thing, Star got off the couch and immediately went outside, where Janna just so happened to arrive to see the events unfold. Then, when she saw Star was nowhere to be seen, she could only turn around to see Star crack her knuckles before knocking her out in one punch.
