Spruce mustered a smile in reply but was unable to speak because of the pain of his leg. He gritted his teeth and looked around.

The Megamall looked like a dark jungle. It would have been impossible to see if the trees hadn't ripped the roof off the mall and if the moon hadn't been shining so bright. Fortunately, the pale, bluish moonlight illuminated everything as though it was a strange, washed-out daylight. In addition to the strong evergreen trees that they had seen growing before, foresty shrubs had sprouted up on the first floor, and ivy and mossy vines had strung themselves across nearly every vertical surface of the mall.

To the left, the Megamall continued its miles-long stretch to the other side.
To the right was an exit just a couple doors away. Another tree had grown up on the other side of the second-floor walkway from where they stood, and thick vines had spread across the exit doors.
In front of them, a walkway led to the South Food Court and a (now-broken) escalator, overgrown with various plants. The branches of a huge oak tree hung over the top of the walkway in front of them, and Karol could see a couple of moving Acorns swinging slightly from some of the other branches.

Spruce, through gritted teeth, asked, "Got any way to cut through those vines?", gesturing with his head to the right.
