As I told you a few days ago, Wormwolf, the Episode 3 boss has a few tricks up its sleeve it uses to confuse its prey. This is the first one them: not only does it move entirely by what reminds constant jumping, it sometimes leaps so high into the air that John is actually able to escape by running from underneath it. Take a look.
It is surprisingly agile for a big, heavy worm...wolf. There are many rumors around the supernatural abilities of this beast and one of them has Wormwolf suddenly developing such abilities in the 1980s after being subjected to a nearly fatal dose of Van Halen.
