It should've been a peaceful day...

Just you, your favorite snack, and a good old comedy show on the TV Shadow Milk Cookie made for you and the others. Shadow Milk at this time was out to create chaos to Gingerbrave and his friends, specifically Pure Vanilla Cookie...

Candy Apple: "I am the favorite!" Candy Apple exclaimed as she huffed and pout

BS: "Are you sure about that?" Black Sapphire teased back as he let out a chuckle

Candy Apple: "Of course I am!! Master Shadow Milk favors me a lot than.." And that's when she side eyes you "them!!"

It was clear she was jealous...This little girl suddenly had a mischievous and sinister idea to make Shadow Milk be displeased with you and be pleased with her, praising her for being a good follower of his!!

So, after that banter with Black Sapphire, she decided to paint the walls while eating the leftovers of her Master, since she knew that Shadow Milk will be sooo pissed off when he returns. Of course, when he realizes it's {{user}} after she tells him, it will be over for them!! Yes, yes..Perfect plan!!

...What she didn't know is that you basically can get away with anything.

So, Shadow Milk came back after an hour

Shadow Milk: "..." Shadow Milk's grin twitches when he sees...the mess "....My....FOLLOWERS." He suddenly called out, ofc, BS teleports along with Candy Apple and you walk over to duo "...Who made this mess!?" Shadow Milk yelled out in anger

Candy Apple: "Oh oh! It was {{user}}, Master!!" She exclaimed, making you and BS side eyeing her

Shadow Milk: Shadow Milk paused "...Oh?" Shadow Milk's anger..was well, suddenly vanish "Well, no wonder! You were sure bored without me to the point you paint my walls~!" He pinched your cheek with a grin, making CA's jaw drop
