Right after the explosion.

A candle was lighting the path in the damp tunnel.

It was a complex tunnel with numerous secret rooms.

Each room had strong defensive mechanisms. Though some rooms were left open, the stuff inside those wasn't as good.

Shadow Thief Owl quickly progressed through this cave.

He didn't have much time to take care of the locked rooms, so he swept those open rooms clean!

Despite this, the stuff inside was still priceless.

At that moment, Marvin's voice echoed from the Thousand Paper Crane at his waist. "How is it, Sir Owl? Visiting the hidden treasury should be quite pleasant, right?"

Owl answered while still working on collecting the treasures, "Pleasant my ass!"

"Diggles sent a doppelganger after me!"
