King Sketch

From Into the Wilds Wiki

King Sketch was a little, white-furred, were-rat creature who was running a drug business (primarily in the mushroom trade), alongside other disreputable businesses within Myste-Hass.
Sketch could change in and out of human form. Originally, these were creatures had traveled from Brindle.
Sketch clearly had paid men within the Myste-Hass militia.
Eventually, a group confronted King Sketch on his boat - The Crab Finder - and killed the little rat and his cronies.
