"You! Explorer! Can you count in groups?" called the Elder with silver stripes on each antenna. "Everything for the festival must be arranged in exact group sizes. We have four hundred and eighty lanterns. They must go in groups of ten."

But it didn't look threatening. It was mimicking the grouping patterns of the festival lanterns โ with its own vine bundles.
