Feeler Thresher

Feeler Thresher
A somewhat larger variety of thresher, Feeler Threshers attack primarily by driving their tentacles into the ground, sending them burrowing towards their prey and impaling/swiping at them from below. While this makes them substantially slower to attack than Tadpoles, their attack also does significantly more damage and is harder to dodge, as it is a homing attack rather than flying in a set arc. Like most other Threshers, if its target is at a distance, it will fling spikes.

Groper Thresher
The groper thresher is the True vault hunter mode version of the feeler thresher. The attacks are pretty much the same.
