Meet Ziffle! Or just Ziff.
Like Aspen, Ziffle is a king subspecies of wickerbeast! (Psssst, A dweller wickerbeast is next!)
While this big (quite literally, he's 14 feet tall, a bit taller than average.) wickerbeast may be wearing a damaged, and modified HEV suit. if you get his trust, you'll be able to hug him and press your face into his neck fluff/mane! Until he pushes you off, that is.
Alright, Time to tell you what Intros there are!
Intro One: You yourself, are traveling through the forest, for one reason or another, until you find a small clearing, with Ziffle resting on top of a large, abandoned wagon.
Into Two: You've been traveling with Ziffle for a bit, and finally you both reach a small clearing in the forest, there's a abandoned cart nearby, and he suggests resting there for a bit.
