Nyx and Twilight returned to their chambers to find a rather startling state of disarray. The living room nook was filled with stacks of documents; folders, bound volumes, and scrolls. The Quartet were in a tizzy, trying to rearrange the mess around a bemused Ink Spot. Spike was laid out flat, groaning in agony. Ink Spot and Cherry Blossom was doing their bit to tend to him. "What happened?" Twilight exclaimed.
Ink Spot looked up at her apologetically. "Just a minute ago, Spike said something about checking the inbox, and... some mail came through for you," he said. He gestured at the stacks of documents around him. "....All at once."
Twilight and Nyx cringed. The visible volume of paper and parchment easily outmassed the first 'bulk delivery' Spike had brought through by a sizable portion. "But I thought that new spell on Spike's fire was supposed to prevent this sort of thing," Twilight said.
Spike looked up and groaned. "U-urgent rush delivery," he said weakly. "No hold..."
"I guess it needs adjusting," Ink Spot said lamely.
Nyx wrinkled up her nose. "What's that smell?" she said. There was a sulphurous odor in the air, like cheap fireworks.
"Some of them... didn't come out the right way," Ink Spot said, cringing.
"It was terrible, your Highness," Cherry Blossom said, distraught. She rubbed the dragon's tummy and plied him with a glass of ginger beer. "He started screaming and flames started shooting out of both ends and---" It was then that Twilight noticed that Spike's rump was planted hip deep in bags of ice.
Twilight grimaced, eyes wide. "Eee-Yiiii."
"M-mistake in the zip code..." Spike burped.
