Deep in the bowels of Canterlot Castle is a special laboratory where Princess Twilight, in her minuscule spare time, conducts experiments, many of them on a strange substance. But her supply of it is getting low, and she is sorely missing the special stallion who provides said substance. As her Friday duties come to an end, time can be afforded to both the stallion and extracting the goods she desires.
