Doodled this during a break from works. I can't believe I haven't made a single drawing of Starchaser and Agate Quartz spending some quality time together until now.
These two share a strong family bond just like Twilight shares with Spike. Ever since Spike brought Agate with him to live in Twilight's castle Starchaser immediately fell in love with her new baby cousin. She was eager to teach him things and play together as they grew up with each other's company. And one of the many things they enjoyed doing together was teaming up to grab some sweets that were out of their reach. Their main target was the cookie jar that was filled with Pinkie's delicious homemade chocolate cookies.
