"The swarm is coming, the swarm is coming!" Nasi cried as he ran down the main street toward the town lord's mansion.

People quickly closed their windows and then rushed out to the street to make sure everything was ready. Shops shooed out their customers and locked up.

If Nasi said it was time, it was time.

Behind the town lord's mansion, fields of flowers were in full bloom, grown specially every year.

And every year Nasi waited to spot the great clouds of butterflies heading toward the town to make sure everyone could fully enjoy them.
