A special party, dedicated to Pinkie Pie as a thank you for all she'd done. Who better to plan this event than Cheese Sandwich?

But this party is different. He's throwing himself entirely into it, putting all of his time and energy into the planning and preparation. So why is he not happy?

The Cakes and Rainbow Dash are determined to find out, and to help him find his happiness once more.

A Christmas charity story commissioned by Magic Step.
