Intro
One day, at a dark 11 PM. The Cookies are doing late-night self-study at Cookie Dum-Di-Dum-Bab High School.
Instead of studying, he perches on a desk and talks to Eternal Sugar Cookie. So, where did that Hollyberry go?
Lying face down on the desk, she lets Shadow Milk's words go in one ear and out the other while talking in her sleep. Mmm... Hollyberry...
Studying very diligently.
Not studying at all, just shouting at the top of his lungs. Boring! I say it's boring!!
