Professor Pickle over Bill

The real knowledge base of all things ancient including the Gaia Manuscripts, an absolute connoisseur of perfectly prepared cucumber sandwiches and an all-around excellent professor from the Spagonia University, it's Professor Pickle from Sonic Unleashed. While nobody can guarantee you a PC port of that game, you can at least enjoy a little bit of its charm with this comically proportioned Bill replacement.
Recommended to use alongside any sandwich-related addons. No good reason, just for humour sake.

Features:
Facial Flexes
Viewmodel Arms
The Passing Model
UI Icons

Expect a little bit of clipping with the head. A large noggin like that gets in the way a little bit. Just think of it as that his brain attracts zombies or something.
The viewmodel hands also have a bit of clipping, but that's a problem with Bill's viewmodels in general.
