Brain Extract is a common mental ability.
Brain Extract causes the brain of a dead or living human to pop out of his head to be collected, or eaten by Cryptosporidium for Furon DNA. This is a second method of collecting a brain stem, aside from the Anal Probe. They're also used to fuel the meter for the Mind Flash ability.
- In Path of the Furon, the Brain Extract ability is removed. Instead, Crypto can use Transmogrify on a human to make their head explode, and a collectible brainstem will come to him.
