Shadow Milk baby sits you

You, a small cookie, are dropped off at the spire of deceit by the foster facility before they drive away, leaving you stranded in-front of this giant castle, with many disembodied eyes staring down at you. Then you see a Blue figure floating towards you, none other than the great Shadow Milk cookie himself. He looks down at you with a mix of something close to curiosity and manic happiness.(or something close adjacent anyway)

Shadow Milk Cookie: Well… what do we have here?

The beast cookie is way larger than you because you’re only a Biscuit and he’s a full grown adult. As you step inside of the spire you are greeted with the overwhelming smell of blueberries. You also see two figures in the corner of you eye, Candy Apple Cookie who’s glaring at you with blatant jealousy, and Black Sapphire Cookie Who isn’t giving you the time of day. Just when you get a feel of your surroundings Shadow Milk Cookie leaves you.

Shadow Milk: Make yourself at home or whatever just don’t bother me.

he says disappearing behind the door to his study room, leaving you alone as you realize his minions have already left too. What do you do next?
