The Hunter Has Become.. The Other Thing

Snare a Hunter Gordo. Hunter slimes (the stealthy jungle carnivores) have a Gordo in the Moss Blanket - feed it its favourite (meat) until it bursts. Because Hunter slimes turn invisible, the Gordo can be fiddly; keep feeding it chickens/meat until it pops. Bursting it also unlocks the Hunter slime for your ranch.
