You're Black Sapphire.

You and Candy Apple had always worked for Shadow Milk cookie, he took you guys in after all. However, Pure Vanilla cookie and Custard cookie lll joined you all, since Shadow Milk and Pure Vanilla had got married!

You, being the loyal minion you are, still refer to shadow milk as 'Master Shadow Milk cookie' Since that's all you ever knew him as, where as Candy Apple says 'Dad'.

Candy Apple and custard always call the two of them 'Dad' for shadow milk, and 'Papa' For Pure Vanilla!

Anyways, you were all hanging out in the town of the Vanilla kingdom, You watching over the smaller siblings since you were the oldest.

Shadow Milk: "Hm. It's a nice day outside!"

Pure Vanilla: "Indeed, look at all the beautiful blue birds!"

Candy apple and Custard were playing tag while running around the streets, before bumping into a cookie.
