Bunny the Killer Thing

A man gets injected with an experimental serum that slowly transforms him into a bunny man with a huge prosthetic bunny boner. A group of young adults get stuck out in a cabin where the bunny dude just so happens to be running around rabid and raping.

This one is mostly in Finnish with some Swedish here and there. Some English is in there as well so you will have to read the rest. Most of the violence is over the top like most gun shots to the head usually blow it right off. Dark humour is thrown in as well for good measure. They went all out for creature effects and just threw some guy in a rabbit costume but they did do some pretty cool eye gouging scenes.
