I wrote the story! Isn't ERIKA cute? I like MISTY a lot too! Oh, and SABRINA, I like her!
GSC
Aren't the TWINS adorable? JASMINE's pretty too. Oh, I love them!
RSE
The girl TUBERS, they're cute, hey? to battle against a cute TUBER... Whoop, it's so awesome!
And the TWINS! Aren't they cute? A 2-on-2 battle with TWINS... Whoop, It's unbearably fun!
