Celestia and Luna enjoy sweets like any other pony. However, unknown to all but the sisters, one kind of dessert satisfies the royal tongue: chocolate pudding crafted by a legendary patissier. The sisters take turns in savoring every cup to reward themselves for a job well done. The conditions were clear: just one cup per shift.

But when a distraught Luna discovered that the sisters' weekly stash had been wiped clean, she pinned her sister for betraying her trust. Knowing well that her sister is adamant about demanding her daily cup of chocolaty goodness, Celestia summons Twilight to hunt down the pudding purger.
