Bigwig is the tritagonist of Watership Down. He is a strong rabbit known for the tuft of hair on his head from which his Lapine name, Thlayli (literally translating to "fur-head"), is derived. He was part of the Sandleford Owsla with Silver and Captain Holly.
There are roughly one-sh*t billion tropes so PLEASE look through them before adding one. Otherwise add what you like. ADDITION: PLEASE read through the trope description provided before submitting something.
