Silverweed

Silverweed belongs to Cowslip's warren and, like Fiver, is a Seer. Unlike Fiver, this ability has twisted him, until he is pretty much insane (hence, the drooling and rolling eyes. ) He composes morbid poetry, reflecting the unnatural, evil situation his warren has put itself in, but since he's so young (Hazel remarks on this with surprise) , he would have been unlikely to really know or understand what was wrong. Like Fiver, his prophetic, and even empathetic abilities can feel the evil around him, but he can't escape, or doesn't know how, so the darkness has pretty much taken him over.

When Fiver and the others come to Cowslip's warren and meet Silverweed, Fiver freaks out and refuses to stay in the warren at all. He tells Hazel that he understands Silverweed better than anyone else could, because Silverweed is himself, if Fiver had been born into such a warren. At any rate, Silverweed terrifies Fiver.

For Silverweed's design, I purposely gave him very mottled fur, almost as though he's got bruises. I've actually seen rabbits with these strange markings, and I immediately thought of this poor, crazy little guy. His eyes are also a bit bloodshot, and the irises are blood red, just for the creepy factor XD
