Fleas

Overview

The Caravan are a group of NPCs in Hollow Knight: Silksong teased by Matthew "Leth" Griffin in the Hollow Knight Discord after members solved a riddle.

Little is known about this group except for a description and a gif also provided by the same source.

"You’re a traveller? A kindred spirit! We hear it's good luck for wanderers to meet on an unfamiliar path. It’s luck we need too, for these roads are haunted and danger snarls at us from every dark corner. Our caravan has only a single, humble wish, but it seems now as though it will never be granted..."

A friendly band of travellers trekking the dangerous roads of Pharloom in search of something precious. Masters of the journey, their caravan boasts a bounty of flavourful food, powerful drinks and some surprising amenities. They wish to gather the playful young fleas scattered across the kingdom, but this land is far more dangerous than they thought.

Flea

Fleas are creatures found sleeping throughout Pharloom. When Hornet approaches a Flea it wakes up, lets out a yawn, and then flies off into the foreground — presumably to be taken in by the Caravan. They are described as a "lovely little gentle flea" who have "come to Pharloom for enlightenment".[1]

Getting them all and completing the wish will make a boss, located where the caravan will stay, disappear.
