The North Cache
"There's really no secret about this," grumbled Louie, as they started their short walk southwards.
"It would be secret enough if we did not have the clues," said Scrooge. "In the story, the maroon Ben Quack was left ashore because he couldn't find any treasure after a week of searching"
Their way led over a short rise, and resulted in disappointment. The treasure had obviously been dug up some weeks ago, the bar silver was gone!
"Awk!" gasped Scrooge.
The nephews scowled.
Launchpad took a closer look.
"The grass hasn't grown in yet," he said. "Someone must have dug it up in the past few months. Otherwise all that would be left would be a grassy slope or some sort of puddle."
"Blast me bagpipes!" complained Scrooge.
"I will blast more than that" interjected Magica Despell. "I have been waiting for you here all morning!
"You WITCH!" Scrooge exclaimed. "What have you done with Flint's treasure!
"What have I done with it!" Magica screamed. "I arrived on the island at dawn, looking for the pirate weapons! They have been stolen. I came here for the silver! It's also gone! Where are my pirate weapons?" she demanded. "What have you done with Flint's silver?"
"How should we know?" Launchpad replied, but in a slightly subdued voice. "We just got here!"
"Don't tell me Launchpad's afraid of Magica?" Louie whispered to Huey.
"Not afraid," Dewey interjected quietly. "Sort of nervous. Launchpad's adventures don't involve much of this weird magical stuff."
Meanwhile, Scrooge was considering the question. Suddenly, the metaphorical lightbulb lit up.
"How should we know! Great Scott! I should have known!" said Scrooge to himself.
"Well, where have you hidden the treasure!" said Magica.
"We haven't got it," Scrooge replied. "Mount your overgrown whiskbroom and fly away."
Magica scowled, but her countenance unexpectedly broke into a malevolent smirk.
"I don't know if you have treasure or not, Scroogie darling" Magica said. "But I am not going anywhere right not, and neither are you, never."
Magica laughed.
"I have you, nephews, and pilot alone here, on this island of evil memory. I will finish with you here, now and forever, and go back to Duckburg and steal your number one dime.
"Dream on," scoffed Scrooge.
"You'll never get Uncle Scrooge's lucky dime," said the nephews, in unison.
"You and what army!" Launchpad put in.
"Ah, Launchpad darling, you should have asked me "you and what navy!" Magica cackled.
Note: What business do I have suggesting Launchpad is afraid of Magica? Or nervous about Magica's magic. In Magica's Shadow War Launchpad seems to be afraid of the shadows and unusually nervous about the crisis, at least in comparison to his usual demeanor. In The Golden Fleecing, Launchpad is terrified of the Harpies, which is in sharp contrast to his usual attitude to non-supernatural foes.
There's also the fact that Launchpad is seldom seen in the same episode as Magica DeSpell
(In fact, I believe there's only two)
Note that I said Magica makes Launchpad nervous, not actually afraid.
